| 摘 要： | 聚苯胺（PAN）具有共轭结构，从理论上满足形成液晶相的基本条件［1，2］．但由于聚苯胺难溶、难熔，长期以来对于聚苯胺溶液（尤其是浓溶液）或熔体的研究甚少．近年来，人们采用具有“增塑作用”的大分子功能质子酸对聚苯胺进行掺杂，获得可溶于多种有机溶剂中的掺杂态聚苯胺［3～5］．然而，聚苯胺溶液的结构与性能的特点及能否产生溶致液晶相等问题目前尚未见报道．为此，我们研究了十二烷基苯磺酸（DBSA）掺杂聚苯胺在有机溶剂中形成液晶相的条件，探讨了不同掺杂方法对PAN－DBSA的溶解性及形成液晶棺的影响；采用差式扫描量热分…

| Abstract: | Polyaniline thermal doped with dodecylbenzene sulfonic acid was found to form a liquid-crystalline solution in m-cresol. A polarizing optical microscope and X-ray diffraction measurement were used to study the texture of liquid-crystalline phase. The doped methods had a great effect on the solubility of PAN-DBSA in organic solvents and the appearance of lyotropic liquid crystal of PAN-DBSA solution. An ordered smectic structure with a layer spacing of d=3. 309 nm can be observed for the thermal doped PAN-DBSA in m-cresol. |
