    研究了十二烷基三甲基己酸铵(C12NC6)与十二烷基苯磺酸钠(SDBS)复配体系的表面活性及应用性能。结果表明,复配体系的临界胶束浓度(cmc)和临界胶束浓度下的表面张力(γcmc)均比单一表面活性剂的低,其扩散吸附速率较单一表面活性剂的慢;复配体系中SDBS的加入可提高C12NC6的稳泡性、润湿性;当n(C12NC6)∶n(SDBS)=1∶1时,复配体系的cmc和γcmc达到最低,具有较好的稳泡性和润湿性,但发泡性和乳化性变差。 Surface activities and application performances of dodecyltrimethylammonium hexanoate (C12NC6) and sodium dodecyl benzene sulfonate (SDBS) blend systems were measured.Results show that the critical micelle concentration and surface tension of the blend systems are lower than each single component surfactant of the system;and the rate of diffusion adsorption of the blend systems is slower than that of each single component surfactant.The foam stability and wetting power of C12NC6 are improved by the addition of SDBS.As n(C12NC6)∶n(SDBS)=1∶1,the critical micelle concentration and surface tension of the blend system achieve the lowest value,and the blend system displays better foam stability and wetting power,but the foaming power and emulsifying power of the blend system become worse.

    摘要 ( 335 )   PDF(2236KB) ( 319 )  
    从3方面综述了离子液体表面活性剂与生物活性分子的相互作用。亲油性的离子液体表面活性剂可与β-环糊精形成1∶1,1∶2或2∶1型包合物,而亲水性的离子液体表面活性剂不能与β-环糊精形成包合物,这些包合物的形成影响了表面活性剂的cmc和在界面的吸附。离子液体表面活性剂能够与牛血清蛋白、β-酪蛋白、溶菌酶等蛋白质相互作用,影响蛋白质的分子构型以及在油/水界面的吸附状态。离子液体表面活性剂与DNA的相互作用主要来源于静电吸引和疏水作用。 Interactions between ionic liquid surfactants and bioactive molecules were summarized in three aspects.Hydrophobic ionic liquid surfactants can form inclusion complexes with β-cyclodextrin (β-CD) according to ratio of 1∶1,1∶2 or 2∶1;while hydrophilic ionic liquid surfactants cannot.The cmc and adsorption of ionic liquid surfactants at interface are affected by the inclusion complexes.The molecular structure and adsorption of protein at the interface between water and oil are affected by the interaction of ionic liquid surfactants with varied kinds of protein,such as bovine serum albumin,β-casein and lysozyme.The interactions between ionic liquid surfactants and DNA are caused by electrostatic attraction and hydrophobic action.

    以单因素试验为基础,采用响应面法优化了直链烷基苯磺酸(LABSA)中的游离硫酸脱除工艺,并比较了游离硫酸脱除前后的LABSA样品的金属腐蚀性和贮存稳定性。结果表明,当氢氧化钙的质量分数1.25%,反应时间3.4 h,反应温度69 ℃,游离硫酸脱除率可达到100%。游离硫酸完全脱除后,金属的腐蚀性可显著降低,上部的ST37-2钢板质量损耗降低了63.16%,中部降低了71.88%,下部降低了67.82%。LABSA样品在35 ℃贮存2个月后,色泽基本保持不变,为29 Hazen。 Based upon results obtained from single factor experiments and in combination with response surface method,the eliminating technique of free sulfuric acid mixed in linear alkyl benzene sulfonic acid product was optimized.Performance of corrosion on metals caused by treated LABSA and untreated LABSA samples as well as their storage stability was compared.Results show that the optimum removal conditions are as follows:adding 1.25% Ca(OH)2,reacting at 69 ℃ for 3.4 h.Under the above conditions,the removal rate of free sulfuric acid can be near to 100%.When the free sulfuric acid is removed completely,the corrosion on steel is reduced obviously.The weight loss of upper part of the ST37-2 steel plate sample is reduced by 63.16%,whiles the middle part and lower parts is 71.88% and 67.82% respectively.After storage at 35 ℃ for 2 months,the color of treated LABSA is 29 Hazen,which indicates that no significant color change happens.

    采用失重法、交流阻抗法和极化曲线法研究了盐酸介质中壳聚糖及其与十六烷基三甲基溴化铵(CTAB)复合缓蚀剂对Q235钢的缓蚀性能。测试结果表明,单独使用壳聚糖作为缓蚀剂,对Q235钢表面有较强的缓蚀性能。当壳聚糖的质量浓度为0.1 g/L时,在1.0 mol/L的盐酸介质中30 ℃腐蚀24 h,3种方法测得的缓蚀效率均达到85%以上;加入CTAB后,缓蚀性能明显增强,CTAB的质量分数为10%时,缓蚀效率达到了92%以上。2种缓蚀剂在Q235钢表面吸附机理不同且吸附过程相互补充,因此二者复配后缓蚀性能加强。 Corrosion inhibition performance for Q235 steel in acidic medium with chitosan and chitosan/cetyltrimethylammonium bromide (CTAB) blend system was studied with three methods (weight loss,potentio-dynamic polarization and electrochemical ac-impedance spectroscopy (EIS)).Results indicated that the inhibition efficiency is good that achieves 85% when the chitosan with mass concentration of 0.1 g/L is used as inhibitor alone and under conditions of corrosion medium,1.0 mol/L HCl;temperature,30 ℃ for 24 h.After addition of CTAB,the corrosion efficiency is significantly enhanced.When the mass fraction of CTAB is 10%,the inhibition efficiency reaches 92% and even higher.Both chitosan and CTAB show the corrosion inhibition performance.Their surface adsorption mechanism is different.However,when they are blended together,there is synergic effect and the corrosion inhibition efficiency is enhanced.

    以高纯木浆板为原料制得再生木浆纤维素(W-RC),并用TEM、FT-IR和XRD对其进行表征,说明W-RC属于典型的纳米基纤维素Ⅱ型颗粒。以辛酸/癸酸甘油三酯(GTCC)为油相,W-RC为乳化剂,制得O/W型Pickering乳液,并通过光学显微镜、荧光显微镜、FE-SEM及流变仪对乳液进行表征。荧光显微镜与FE-SEM的结果显示W-RC吸附在油/水界面并在微球表面及微球间形成三维网状结构。流变学表明W-RC及由其稳定的乳液具有典型的剪切变稀特性。W-RC具有优良的乳化性能,在W-RC质量分数为0.6%、分散相体积分数高达60%时,也能得到稳定的乳液。 The regenerated wood pulp cellulose (W-RC) was prepared with high purity wood pulp board as raw material and the product was characterized by TEM,FT-IR and XRD.Results indicate that W-RC belongs to the typical nanometer cellulose Ⅱ particles.O/W Pickering emulsion was prepared using caprylic/capric triglycerides (GTCC) as the oil phase and W-RC as the emulsifier.The Pickering emulsions were characterized by optical microscopy,fluorescence microscopy,FE-SEM and rheometer.Results show that W-RC is adsorbed at the oil-water interface and a three-dimensional network structure is formed on and in between oily microspheres from fluorescence microscopy and FE-SEM image.The rheology study illustrates that W-RC and the resulting emulsions feature the typical shear-thinning property of emulsions.W-RC displays excellent emulsifying properties,and a stable emulsion can be obtained when the W-RC mass fraction is 0.6% and even if the dispersed phase volume fraction is as high as 60%.

    以十六烷基三甲基溴化铵(CTAB)作为疏水改性剂,利用湿法球磨对蒙脱土(MMT)进行改性,制备了插层型的改性蒙脱土(CMMT)。采用SEM、zeta电位分析仪、FT-IR、XRD、TEM和TGA对CMMT进行表征。进而,以两亲性海藻酸衍生物(Ugi-Alg)协同CMMT来稳定Pickering乳液,探究改性剂添加量不同时制备的CMMT对Pickering乳液稳定性的影响。实验结果显示,CTAB在湿法球磨的机械作用下插入了MMT微粒片层中。Ugi-Alg吸附于CMMT微粒表面,使CMMT微粒在油/水界面的聚集能力增强。当CTAB的添加量为1.0倍CEC时,CMMT微粒的带电量最低,乳液稳定性最高。 The intercalating modified montmorillonite (CMMT) was prepared by wet type ball mill process with montmorillonite (MMT) as basic material and hexadecyltrimethylammonium bromide (CTAB) as hydrophobic modifying agent.Then the product CMMT was characterized by SEM,zeta potential analyzer,FT-IR,XRD,TEM and TGA.Furthermore,stable Pickering emulsions were prepared by CMMT in cooperation with amphiphilic alginic acid derivative (Ugi-Alg),and then the effect of the CMMT that modified with varied amount of CTAB on the stability of Pickering emulsion was investigated.Experimental results show that the CTAB is intercalated into the lamella interlayers of MMT micro-particulates by the mechanical action of the ball mill.Ugi-Alg is adsorbed on surface of the CMMT,that enhancing the aggregation capacity of the CMMT particulates at the oil-water interface.When the addition amount of CTAB is 1.0CEC,the charge of CMMT particulates is at the lowest while the emulsion stability is the highest.

    使用Mimedisc作为支架,接种正常人真皮成纤维细胞,经过3周培养形成类似真皮结构,然后在其上接种正常人表皮角质细胞,依次经过浸没培养阶段和气-液相培养阶段,最终在体外形成3D皮肤结构模型。通过Masson染色及一系列免疫荧光染色显示此3D皮肤模型有近似真实皮肤的结构及关键蛋白表达。以此模型为工具研究了活性物喜马拉雅雪松精粹对皮肤真表皮连接处(DEJ)的作用。结果显示喜马拉雅雪松精粹可以明显提高表皮的厚度,增加皮肤抵抗外界环境的屏障能力,并且可以显著促进DEJ重要蛋白层粘连蛋白5(Laminin 5)和VII型胶原蛋白(Collagen VII,Col VII)的表达,使Laminin 5上调20%,Col VII上调47%,具有应用于抗衰老类化妆品的潜力。 Via the use of Mimedisc® as a scaffold,the normal human dermal fibroblasts were first seeding into the scaffold to form a dermal equivalent after 3 weeks;and then seeding normal human epidermal keratinocytes on it,followed by immersion and air-liquid inter-phase culture stage,to finally form a 3D sponge matrix skin model which has a very similar structure of normal human skin (NHS).The results of Masson staining,immuno-histochemical (IHC) and immuno-fluorescence (IF) staining show that this skin model displays a very similar structure and key protein expression of NHS.Meanwhile,this model was used as a tool to investigate the effect of Himalaya cedar extract on Dermal-Epidermal Junction (DEJ) in vitro.Results show that the Himalayan cedar extract can significantly increase the thickness of the epidermis,thus increase the barrier capacity of the skin to resist external environment.Further,the Himalaya cedar extract can promote the expression of Laminin 5 and Collagen VII of DEJ.The expression of the Laminin 5 and Collagen VII increases 20% and 47% respectively.So the Himalaya cedar extract displays the potential to be applied in development of anti-aging cosmetics.
