| 摘 要： | 以极性有机物为溶剂制备展状液晶已经引起重视,但关于极性有机溶剂对层状液晶结构和稳定性影响的研究还很不够.我们曾以~2H NMR测量研究了以甲酰胺代替甘油为溶剂,对非水层状液晶SDS/C_(10)H_(21)OH/溶剂体系稳定性的影响.本文则以小角X射线衍射测量,研究以甲酰胺代替甘油后,对层状液晶SDS/C_(21)H_(21)OH/溶剂体系结构的影响。

| Abstract: | The interlayer spacing of lamellar liquid crystal decreased with increase of theweight ratio of decanol/SDS at constant solvent content in the system of SDS/decanol/glycerol, but increased in system of SDS/decanol/formamide. At a constant weightratio of decanol/SDS, tbe interlayer spacing decreased when formamide was used assolvent instead of glycerol. These results are related to the effects of hydrogen bondformed between solvent and SDS, decanol and the similarities of glycerol and decanolfor the penetration of the solvent in to the lamellar liquid crystal. |
