摘要： 研究了无患子皂苷与十二烷基苯磺酸钠(SDBS)复配体系的表面活性,并将其应用于氢氧化镍复合材料的制备中;采用X射线衍射(XRD)和扫描电镜(SEM)对复合材料进行了结构表征,考察了表面活性剂对材料形貌的影响。研究表明,自提无患子皂苷临界胶束浓度(cmc)和对应表面张力(γcmc)分别为0.200 g/L和38.3 mN/m;在复配体系中,当SDBS的质量分数为5%时,两者表现出协同作用,而当SDBS的质量分数增至20%后,则呈现对抗作用;以SDBS质量分数为5%的表面活性剂复配体系作为添加剂,在0.83 g/L时,制备得到直径约为3 μm形貌均匀的球状氢氧化镍复合材料。

Abstract: Surface activity of Sapindus mukurossi saponin and sodium dodecyl benzene sulfonate (SBDS) blend system was examined,and the blends were used to prepare nickel hydroxide composites.The composites were characterized with X-ray diffraction (XRD) and scanning electron microscope (SEM).Influence of the surfactant on morphology of the composites was investigated.Results revealed that the critical micelle concentration (cmc) and the surface tension (γcmc) of the extracted Sapindus mukurossi saponin are 0.200 g/L and 38.3 mN/m respectively.The blend system displays synergic effect when mass fraction of SDBS achieves 5%,while confrontation effect when mass fraction of SDBS is more than 20%.Using the blend system composed of 5% SDBS as additive at dosage of 0.83 g/L,homogeneous morphological microspheres of nickel hydroxide composites with average diameter of 3 μm can be successfully prepared.

Key words: Sapindus mukurossi saponin, sodium dodecyl benzene sulfonate, blend system, nickel hydroxide, composites
