十二烷基硫酸钠中相微乳液的液晶结构

Structure Study of Liquid Crystal in Sodium Dodecylsulfonate Middle Phase Microemulsion

微乳液是指油、水、表面活性剂、助表面活性剂形成的各向同性的、光学透明或半透明的热力学稳定体系．中相微乳液是指富表面活性剂相与过剩水相、过剩油相形成的三相体系．中相微乳液既可增溶水，又可增溶油，且与过剩水相、油相超低的界面张力，因而在强化采油中引起人们...

Phase state and structure of liquid crystal in sodium dodecylsulfonate middle phase microemulsion were studied. The following facts has been proved by ~2H NMR quarsplitting and small angle X-ray diffraction techniques, two kinds of lamellar liquid crystal were coexisted in suitable salt concentration. Order parameters of liquid crystal were calculated from ESR anti-isotropic spectrum.
