研究了十二烷基苯磺酸热反应掺杂聚苯胺溶于间甲酚中形成的液晶溶液，探讨了在外界力场和电场作用下，此液晶溶液的流变性和导电性随溶液浓度和温度变化的规律；并采用偏光显微镜技术和Ｘ射线衍射分析等方法对聚苯胺液晶相的结构进行研究。结果表明，十二烷基苯磺酸掺杂聚苯胺／间甲酚溶致液晶为二维有序的近晶相层状结构，液晶相的产生使溶液的剪切粘度和导电率在相转变点处发生突变 The liquid crystal solution of diallylbenzenesulfonic acid doped with polyaniline dissolved in m-cresol was investigated. The rheological and electrical conductivity of this liquid crystal solution were investigated with the solution concentration and Temperature variation law; and the use of polarized light microscopy and X-ray diffraction analysis of the polyaniline liquid crystal phase structure. The results show that dodecylbenzene sulfonic acid doped polyaniline / m-cresol lyotropic liquid crystal is a two-dimensional ordered smectic phase-lamellar structure. The liquid crystal phase produces the shear viscosity and conductivity of the solution in the phase transition Point mutation
