黏弹性表面活性剂（VII）—— CO2响应蠕虫状胶束 Viscoelastic surfactants (VII) CO2-responsive wormlike micelles 冯玉军 2026 (7):  833-840.  doi: 10.3969/j.issn.2097-2806.2026.07.001 摘要 ( 1491 )   HTML ( 3 )   PDF(9099KB) ( 65 )   黏弹性表面活性剂领域的核心发展方向之一，在于赋予体系对外部刺激的智能响应能力，从而实现流变性能的可逆按需调控。CO2因其来源广泛、环境友好且去除简便、无盐副产物累积等优势，已成为传统pH调节手段的理想替代触发因子。本讲系统梳理了CO2响应型蠕虫状胶束的设计策略、自组装机制及流变行为特征。CO2响应的本质在于其溶于水后生成碳酸，使长链有机碱发生可逆质子化，进而驱动表面活性剂前体转化为阳离子或“拟双子”型表面活性剂，并自组装为缠结网络，赋予体系高黏弹性；而去除CO2后，去质子化过程使胶束瓦解，体系恢复低黏态。依据分子结构差异，可将现有体系归纳为三类典型模式：阴离子表面活性剂与叔胺助溶物的二元体系，依赖静电构筑动态拟双子结构；单一长链多胺体系，经CO2触发后由囊泡转变为蠕虫状胶束，其质子化产物与碳酸氢根抗衡离子协同促进胶束生长，此为单纯酸滴定所无法实现；超长链叔胺体系，可在常温常压下仅通过CO2与空气的交替鼓泡实现溶胶-凝胶的可逆转变。此外，预先形成的阴离子蠕虫状胶束亦可因CO2诱导羧基质子化而显著降黏，呈现“关闭”型响应。上述研究表明，CO2响应行为不仅依赖于分子堆积参数的协同调控，更受质子化路径及抗衡离子种类的深刻影响，为智能流体设计提供了系统的理论依据与实用范例。 Stimuli-responsive wormlike micelles（WLMs）represent a frontier in viscoelastic surfactant research, enabling on-demand modulation of rheological properties. Among various triggers, CO2 has emerged as an attractive alternative to conventional pH regulation due to its ready availability, environmental benignity, and reversible removal without salt accumulation. This review systematically addresses CO2-responsive WLMs, focusing on molecular design principles, assembly mechanisms, and rheological characteristics. The response behaviour hinges on the reversible protonation of organobases—primarily tertiary amines—upon CO2 sparging, which generates cationic or pseudo-gemini surfactants that self-assemble into entangled networks. Conversely, CO2 removal by inert gas purging or mild heating reverses the protonation, dismantling the micellar network and restoring low viscosity. Three prototypical systems are delineated:（i）binary mixtures of anionic surfactants with amine-based hydrotropes, which form CO2-switchable pseudo-gemini species through electrostatic linkages;（ii）single-component long-chain polyamines, where CO2 induces a vesicle-to-wormlike transition via mixed protonated species and bicarbonate counterions, a pathway unattainable by simple acid titration; and（iii）ultra-long-chain tertiary amine surfactants, which enable reversible sol-gel transitions at ambient conditions using only CO2 and air. Notably, CO2 can also destroy pre-formed anionic WLMs by converting carboxylate headgroups into neutral acid forms, thereby reducing viscosity—a distinct “turn-off” mechanism. In summary, these systems exhibit robust cyclability, precise rheological switching, and structure-property correlations governed by molecular packing parameters and counterion effects. The findings underscore the critical role of protonation pathways and ionic speciation in dictating WLM formation, offering a versatile platform for applications in oilfield chemistry, drug delivery, and smart materials. 数据和表 | 参考文献 | 相关文章 | 计量指标

环氧丙烷与1, 2-环氧丁烷对脂肪醇醚构效关系的影响研究 Investigating the impact of propylene oxide and 1, 2-butylene oxide on the structure-activity relationship offatty alcohol ethers 汪洪洋, 梁慧斌, 王春雨, 张科, 周婧洁, 耿涛 2026 (7):  841-852.  doi: 10.3969/j.issn.2097-2806.2026.07.002 摘要 ( 1091 )   HTML ( 4 )   PDF(2572KB) ( 57 )   为探究环氧丙烷（PO）和1, 2-环氧丁烷（BO）改性对脂肪醇聚氧乙烯醚（AEO7）性能的影响，本研究系统比较了AEO7及其在PO/BO改性下的耐盐性、耐碱性能、泡沫性能、乳化稳定性、润湿性、浊点、冻点及去污性能等关键性质。结果表明，PO或BO基团的引入普遍降低了AEO7的耐碱性，且BO的负面影响更为显著，改性同时改变了其盐耐受性，BO的引入显著降低了产物的水溶性与盐容忍度，PO与BO均能加快泡沫破裂的动力学过程，其中BO改性样品表现更优。由于疏水尾链与油相相容性的改善，改性产物的乳化能力得到显著增强，润湿性能亦获得提升，尤其是BO改性样品。此外，PO/BO的引入导致浊点与冻点明显下降，其降低幅度与疏水基团的类型和接入数量相关；在去污力方面，PO改性提升了对皮脂污布的去污率，而BO的引入则降低了对炭黑污布和皮脂污布的清洁效率。该研究为烷氧基化表面活性剂的定向分子设计与性能优化提供了实验依据与理论指导。 This study aimed to elucidate the impact of propylene oxide（PO）and 1, 2-butylene oxide（BO）incorporation on the properties of AEO7 surfactant. A comparative investigation was conducted on the salt tolerance, alkali resistance, foaming, emulsification, wetting ability, cloud point, pour point, and detergency of the pristine and modified surfactants. The results demonstrated that the introduction of PO or BO groups generally compromised the alkali resistance of AEO7, with BO exerting a more detrimental effect. Modification also altered salt tolerance, and BO incorporation notably reduced water solubility and salt tolerance. Both PO and BO significantly accelerated defoaming kinetics, with BO-modified variants exhibiting superior performance. Emulsifyingability was markedly enhanced due to improved compatibility between the surfactant hydrophobic tail and the oil phase. Wetting performance was also improved, particularly in BO-modified samples. Furthermore, the incorporation of PO/BO led to a distinct reduction in both cloud point and pour point, which showed a clear correlation with the type and extent of hydrophobic modification. Regarding detergency, PO modification improved the removal of sebum soil, whereas BO incorporation reduced the cleaning efficiency for both carbon black and sebum soils. This work provides fundamental experimental evidence and theoretical insights for the targeted molecular design and performance optimization of alkoxylated surfactants. 数据和表 | 参考文献 | 相关文章 | 计量指标

基于分子动力学模拟的PBS-TME/PLA复合材料的制备及性能研究 Preparation and performance study of PBS-TME/PLA composite materials based on molecular dynamics simulation 韩玉英, 陈莉君, 李长伟, 韩家旋, 任莹辉 2026 (7):  853-863.  doi: 10.3969/j.issn.2097-2806.2026.07.003 摘要 ( 1368 )   HTML ( 1 )   PDF(6827KB) ( 42 )   采用分子动力学模拟研究了PBS-TME/PLA复合材料的相容性及力学性能，并以此为基础制备了7种不同配比的PBS-TME/PLA复合材料，采用XRD，XPS法对复合材料的结构形貌进行了表征，并考察了其力学性能、亲水性、水蒸气透过率、降解速率及植物生长情况。分子动力学模拟结果表明，PBS-TME与PLA具有较好的相容性。当PLA与PBS-TME共混后，削弱了PBS-TME的结晶能力，使得PBS-TME/PLA复合材料结晶能力降低，降解速率提高。当PBS-TME与PLA的质量比为8∶2时所形成的复合材料相容性最佳，结晶度为25.39%，综合力学性能最佳（其拉伸强度为15.78 MPa，断裂伸长率为19.56%），与水之间的接触角最小（72.6°），水蒸汽的透过率最大（63.12 g/（m2·d）），且在土壤上清液和酶降解中降解率最高（37.33%和27.85%），青菜叶绿素含量、可溶性蛋白含量、过氧化物酶活性、维生素C的含量均有所提高。本研究扩大了可生物降解材料在实际领域中的应用。 Molecular dynamics simulations were conducted to investigate the compatibility and mechanical properties of PBS-TME/PLA composites. On this basis, seven PBS-TME/PLA composites with different mixing ratios were prepared. The structural morphology of the composites was characterized by using XRD and XPS methods, and their mechanical properties, hydrophilicity, water vapor transmission rate（WVTR）, degradation rate, and plant growth were investigated. The results of molecular dynamics simulations indicated that PBS-TME exhibited good compatibility with PLA. When PLA was blended with PBS-TME, the crystallization ability of PBS-TME was weakened. Therefore, the crystallization ability of PBS-TME/PLA composite materials was decreased and the degradation rate was increased. When the mass ratio of PBS-TME to PLA was 8∶2, the compatibility of the material was the best, the crystallinity was 25.39%, and the comprehensive mechanical properties were the best（with tensile strength of 15.78 MPa and elongation at break of 19.56%）. With the increase of PBS-TME content, the hydrogen bonding between molecules made water molecules easier to enter the interior of the material, and at the mass ratio of PBS-TME∶PLA of 8∶2, the water contact angle was the smallest（72.6°）and the permeability of water molecules was the largest（WVTR was 63.12 g/（m2·d））. Moreover, at the mass ratio of PBS-TME∶PLA of 8∶2, the material exhibited the highest degradation both in soil supernatant and by enzymatic degradation. This composite material allowed sufficient supply of carbon sources and water molecules for plant growth, resulting in the increased chlorophyll content, soluble protein content, peroxidase activity, and vitamin C content in green vegetables. This work might expand the application of biodegradable materials in practical fields. 数据和表 | 参考文献 | 相关文章 | 计量指标

The crystal structure, microstructure, spectral properties and pore characteristics of Ag-Fe3O4 nanomaterials were characterized by XRD, SEM, XPS, UV-vis, FTIR and nitrogen adsorption-desorption tests. Their adsorption performance for Cr（VI）in wastewater under different conditions was simulated. The results showed that the Ag-Fe3O4 nanomaterials prepared by solvothermal method hadanti-spinel structure and exhibitedhigh crystallinity. Ag had been successfully chemically loaded onto the surface of Fe3O4 through the interfacial Ag-O-Fe bonds, and the morphology was rough spherical particles. The sample loaded with 3% Ag exhibited the narrowest band gap of 2.77 eV and the longest absorption edge of 446 nm, with a maximum of specific surface area of 588.6 m2/g and a pore volume of 0.418 cm3/g. The loading of Ag significantly enhanced the performance of Fe3O4 nanomaterials for adsorbing Cr（VI）in wastewater. The sample containing 3% Ag achieved a Cr（VI）removal as high as 96.99% within 240 min, indicative of the most outstanding removal effect. With the increase of the dosage of functional nanomaterials, the adsorption effect was enhanced. The adsorption effect of the sample containing 3% Ag reached the maximum value of 99.24% at pH of 1, and theremoval of Cr（VI）could still maintain over 85% after 5 cycles, indicative of excellent cycling stability. 数据和表 | 参考文献 | 相关文章 | 计量指标

Its structure was characterized by 1H NMR and FT-IR, which confirmed that the target product was successfully prepared. Then cotton knitted fabrics were treated with this antistatic agent by impregnation method. The effects of antistatic agent mass concentration, impregnation time and baking temperature on the antistatic performance of cotton knitted fabrics were systematically studied. The results showed that when the antistatic agent mass concentration was 1.5 g /L, the impregnation time was 40 min, and the baking temperature was 170 ℃, the static voltage half-life of the treated cotton knitted fabric significantly decreased from 61.62 s to 11.33 s, and the peak static voltage dropped from 1 516 V to 719 V, indicative of excellent antistatic performance. In addition, this antistatic agent also endowed cotton knitted fabrics with excellent antibacterial properties, with antibacterial rates against Escherichia coli and Staphylococcus aureus reaching 99.98% and 99.45% respectively. The wash resistance test showed that after 50 standard water washes, the cotton knitted fabric still maintained antibacterial rates of 81.32% against Escherichia coli and 53.34% against Staphylococcus aureus. 数据和表 | 参考文献 | 相关文章 | 计量指标

Subsequently, detailed morphological, crystalline, and photoelectrochemical characterizations were performed. The photocatalytic degradation performance and recycling performance of the PANI/CN@AC composites were evaluated. Furthermore, their charge transfer mechanism and photocatalytic mechanisms were analyzed based on the photoelectrochemical data, active species trapping experiments, and energy band structures. The results show that the semiconductor material CN and the conductive polymer PANI are in close contact, forming a heterojunction, which facilitates efficient separation of photogenerated carriers and broadens the absorption range in the visible-light spectrum. The AC support effectively improves the specific surface area and adsorption performance. Consequently, the PANI/CN@AC composite exhibits excellent photocatalytic and recycling performance. The degradation efficiency of CR under simulated visible-light（λ>420 nm）irradiation reaches 98.97%, and remains at 98.71% after 5 cycles. Mechanistic insights reveal that the conduction band position photoelectron of PANI reduces O2 to superoxide radicals（·O2-）, whereby CR is oxidized and decomposed under the action of active species such as ·O2- and holes. 数据和表 | 参考文献 | 相关文章 | 计量指标

The residual biomass of Cordyceps militaris after cordycepin extraction was ustilized as the raw materials. Cordyceps militaris protein was extracted via alkali extraction-acid precipitation method, followed by the optimization of a multi-enzyme hydrolysis process to produce Cordyceps militaris polypeptides. The scavenging capacities of Cordyceps militaris polypeptides and crude protein against DPPH, ABTS, and ·OH free radicals were determined at different mass concentrations（0.1, 0.2, 0.5, 1.0, 2.0, 4.0 mg/mL）. In addition, HaCaT cells were pretreated with 0.5, 1.0, and 2.0 mg/mL of Cordyceps militaris polypeptides for 24 h, followed by UVB irradiation. At 24 h post-UVB irradiation, cell viability was assessed by the CCK-8 assay; intracellular reactive oxygen species（ROS）levels were measured using the DCFH-DA fluorescent probe method; and the activities of SOD, CAT, and GSH-Px, as well as the cellular content of MDA were detected according to the kit instructions. The activity of the intracellular Nrf2/Keap1 pathway was determined by Western blot. The results show that the degree of hydrolysis of Cordyceps militaris hydrolyzed by the sequential combination of snail enzyme + pepsin + papain + alkaline protease is 84.25%±6.15%, which is identified as the optimal enzyme combination. The IC50 values of Cordyceps militaris polypeptides for DPPH, ABTS, and ·OH free radicals are 1.67, 3.02 and 1.49 mg/mL, respectively. Compared with the model group（M）, pretreatment with low-, medium-, and high-dose Cordyceps militaris polypeptide groups（CMP-L/M/H）and the vitamin C（VC）group significantly increase relative cell viability, decrease relative ROS fluorescence intensity, enhance the activities of SOD, CAT, and GSH-Px, and reduce MDA content, while upregulating nuclear Nrf2 protein levels and downregulating Keap1 protein levels in a dose-dependent manner（P<0.05）.

一种降低月桂醇聚醚硫酸酯钠刺激性的清洁组合物性能研究 Study on the performance of a low-irritation cleaning composition with reducing the irritancy of sodium laureth sulfate 吴明城, 李靖, 伍丽诗, 谢怀统, 史学东, 周攀峰 2026 (7):  919-924.  doi: 10.3969/j.issn.2097-2806.2026.07.010 摘要 ( 81 )   HTML ( 7 )   PDF(1976KB) ( 49 )   以月桂醇聚醚硫酸酯钠（AES）为研究目标，采用红细胞溶血试验、玉米醇溶蛋白溶解试验、鸡胚绒毛尿囊膜试验对AES复配体系刺激性进行研究。结果表明，磺酸羟丙酯月桂基葡糖苷交联聚合物钠（HLC）、椰油酰谷氨酸二钠（UCS）及PEG-80失水山梨醇月桂酸酯（Tween 28）对AES刺激性改善较明显。动态光散射正交试验分析结果显示：影响最大因素为HLC，其次为Tween 28，UCS影响最小，HLC、Tween 28和UCS的添加量均为4%为体系较优组合；泡沫高度正交试验分析结果显示：影响最大因素Tween 28及UCS，HLC影响最小，HLC、Tween 28和UCS的添加量分别为4%，2%和1%为体系较优组合。综合正交试验k值大小分析，确定AES复配体系为4% HLC、4% Tween 28及1% UCS，该组合通过空间位阻与静电斥力的协同作用增大胶束粒径，从而降低AES复配体系刺激性，同时保持丰富泡沫，平衡体系的温和清洁与泡沫丰富度。 Focusing on sodium laureth sulfate（AES）, the irritancy of the AES complex system was studied using red blood cell hemolysis test, zein test, and chicken embryo chorioallantoic membrane test. The results show that sodium hydroxypropyl sulfonate glucoside cross-linked polymer（HLC）, disodium cocoyl glutamate（UCS）, and PEG-80 sorbitan laurate（Tween 28）significantly mitigated the irritancy of AES. The results of dynamic light scattering orthogonal experiment analysis show that the most influential factor is HLC, followed by Tween 28, with UCS having the least impact, with the corresponding optimal combination of being 4% HLC, 4% Tween 28, and 4% UCS. The orthogonal analysis of foam height shows that the most influential factors are Tween 28 and UCS, while HLC has the least influence, yielding an optimal combination of 4% HLC, 2% Tween 28, and 1% UCS. Based on the comprehensive analysis of the value of k in the orthogonal tests, the comprehensive optimal AES complex system is determined to be 4% HLC, 4% Tween 28 and 1% UCS. This combination increases the micelle size through the synergistic effect of steric hindrance and electrostatic repulsion, thereby reducing the irritation of the AES complex system, while maintaining abundant foam, effectively balancing the contradiction between system mildness, cleansing performance, and foaming capability. 数据和表 | 参考文献 | 相关文章 | 计量指标

However, the poor solubility of AAS in oily systems limits their extensive application in bath oils, so currently conventional sulfate-based surfactants remain dominant in bath oil formulations. In this work, caprylic/capric triglyceride（GTCC）was used as the oil phase and laureth-4（LE-4）was used as the emulsifier. Ten AAS were selected as candidates of the key component in bath oil, which were then screened by transparency test combined with pseudo-ternary phase diagram. It was confirmed that sodium lauroyl methylaminopropionate（SLMA）exhibited the best compatibility with the system, featuring a broad region of transparent liquid in the phase diagram and good formulation applicability. Thus it provided a basis for subsequent formulation optimization. The mass ratio of GTCC∶LE-4∶SLMA was optimized to further improve the overall performance of the bath oil, which was determined to be 4∶3∶3 according to the foaming performance test and protein damage assay. At this ratio, the product achieved the foam volume of 127.3 mL, foam half-life of 677.5 s, and protein damage value as low as 0.729 1 g/L, indicative of excellent foaming performance and mildness. Compared with the traditional sulfate system, the SLMA-based system showed better performance in foaming, mildness, and moisturization while maintaining comparable cleansing ability. These advantages could be clearly perceived in consumer testing. In addition, the system exhibited excellent stability in centrifugation and multi-temperature storage tests. Human skin patch test confirmed no skin irritation, indicative of good safety. This work innovatively applied AAS to transparent oily systems for the first time, which provided a new strategy for the development of high-end bath oils with promising industrialization prospects. 数据和表 | 参考文献 | 相关文章 | 计量指标

The samples were extracted with an ultrasonic-assisted treatment at 80 ℃ by using a 1% nitric acid-1% ascorbic acid solution, followed by the purification with n-hexane for defatting. The analysis was then performed by anion-exchange chromatography with gradient elution, by employing ammonium dihydrogen phosphate（pH 8.5）as the mobile phase. The results showed that the six arsenic species were completely separated within 10 min. The standard curves were linear over the mass concentration range of 1-100 μg/L, with correlation coefficients（r 2）greater than 0.996. The limits of detection ranged from 0.9 to 1.6 μg/kg, and the limits of quantification ranged from 2.9 to 5.0 μg/kg. Recovery rates ranged from 86.2% to 102.1%, with precision（RSD）ranges of 1.8%-4.3%. Intra-day and inter-day stabilities were 1.5%-3.7% and 2.1%-4.3%, respectively. The proposed method exhibits good recovery rate, precision, stability, and accuracy, which is suitable for routine determination of six arsenic species in cosmetics. Moreover, it effectively addresses the current gap in the “Safety and Technical Standards for Cosmetics”（2015 Edition）regarding the arsenic speciation, and provides an essential technical support for the future refinement of cosmetic regulatory standards. 数据和表 | 参考文献 | 相关文章 | 计量指标
