摘　　要：研究了双子阳离子表面活性剂在水溶液中形成的溶致液晶的流变性质.根据体系流变性质的变化和偏光显微镜照片发现,随双子阳离子表面活性剂质量分数的增加,体系中依次可以形成胶束、层状液晶、六角状液晶和立方状液晶.用液晶的空间构型解释了实验结果.Rheological properties of liquid crystalline phase of Gemini cationic surfactant water solution were investigated. It was demonstrated that micelle,lamellar hexagonal and cubic liquid crystals and inverse micelle were formed successively in the same system as the mass fraction of Gemini cationic surfactant increased. The critical stresses decrease for the phase transition of hexagonal phase to cubic phase. The results are explained by the special configuration and interaction.
