摘要： 以短链醇乙醇等作为助表面活性剂,能与阴离子表面活性剂十二烷基硫酸钠生成层状液晶;随助表面活性剂直链醇碳链长度增加,层状液晶的生成能力与稳定性皆增加,层伏液晶层间距d值随链长的变化与两亲双层厚度dO值和溶剂渗透率随醇链长变化有关.

Abstract: We found it possible to form the lamellar liquid crystal using alcohol with short chains as a cosurfactant in SDS/CnOH/H2O systems,the stability of the lamellar liquid crystal increased with the chain length of alcohol.The increase of interlayer spacing d with the chain length of alcohol was related to the d0 value and the penetration of solvent in the lamellar liquid crystal.

Key words: surfactant, low angle X-ray diffraction, lamellar liquid crystal
