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ｄ＿Ｏ值和溶剂渗透率随醇链长变化有关．
We found it possible to form the lamellar liquid crystal using alcohol withshort chains as a cosurfactant in SDS/C_nOH/H_2O systems,the stability of thelamellar liquid crystal increased with the chain length of alcohol.The increase ofinterlayer spacing d with the chain length of alcohol was related to the d_O valueand the penetration of solvent in the lamellar liquid crystal.
