摘要
小角X射线衍射表明。在SDS/C_(10)OH/H_2O和SDS/C_(10)OH/甘油二体系的层状液晶中,随重量比C_(10)OH/SDS增加,两亲层厚度k_0不变,但溶剂的渗透率加大,溶剂层厚度减小,致使确定溶剂含量下降,层间距d减小.在确定重量比C_(10)OH/SDS条件下,以甘油代替水作溶剂,层状液晶两亲层厚度d_0不变,但层间距d却缩小.
The measurements of low angle X-ray show that the penetration of solvents in SDS/ C_(10)OH/H_2O and SDS/C_(10)OH/ Glycerol lamellar liquid crystals increased with weight ratio of C_(10)OH / SDS at certain water content so that the interlayer spacing d decreased with weight ratio of C_(10)OH / SDS at the certain water content even if d_0 vaulcs did not change. On the other hand, the properties of solvents had no effects on the d_0 vaulcs of lamellar liquid crystal. The interlayer spacing d, however, decreased when glycerol was used as solvent to replace water at certain weight ratio C_(10)OH / SDS.
