通过流变学手段对聚苯胺溶液的凝胶化行为研究表明，在室温下，聚苯胺（ＰＡｎ）／Ｎ－甲基－２－吡咯烷酮（ＮＭＰ）溶液有一转折浓度Ｃｇ（０．０５ｇ／ｍＬ），浓度高于此值时，浴液凝胶化速度急剧增大，凝胶速度还与溶剂，ＰＡｎ分子量及溶液的温度有很大关系。溶液中不溶的ＰＡｎ的存在会加速凝胶化过程。ＰＡｎ／ＮＭＰ凝胶的假塑性和触变性明显地反映出ＰＡＶＮＭＰ溶液的凝胶化是溶剂参与的ＰＡｎ分子链间的物理交联过程。 The results of gelation behavior of polyaniline solution by rheological analysis showed that the polyaniline (PAn) / N-methyl-2-pyrrolidone (NMP) solution has a transitional concentration of Cg (0.05g / mL) When the concentration is higher than this value, the gelling speed of the bath increases sharply. The gel speed also has a great relationship with the solvent, the molecular weight of PAn and the temperature of the solution. The presence of insoluble PAn in the solution accelerates the gelation process. The pseudoplasticity and thixotropy of the PAn / NMP gel clearly show that the gelation of the PAVNMP solution is a physical cross-linking process between the solvent-participating PAn molecular chains.
