电子型／离子型导电高分子共混物

用苯胺在酸性水溶液中的进行化学氧化聚合合成了能溶于Ｎ－甲基吡咯烷酮的高分子量聚苯胺（ＰＡｎ），并用这种ＰＡｎ与一种高分子固态离子导体－－聚乙二醇聚醚氨酯脲（ＰＥＵＵ）和ＬｉＣｌＯ４的复合物（ＰＥＵＵ－ＬｉＣｌＯ４）进行溶液共混制得了具有电子型／离子型两种导电功能的新型高分子共混物。用差示扫描量热法、动态粘弹仪、应力－应变试验、四探针法和交流阻抗谱对这种高分子共混物进行研究。实验结果表明，上述ＰＡｎ

Electronically/Ionically Conducting Polymer Blend

In this work, a high molecular weight polyaniline (PAn) which is soluble in N methy1 2 pyrrolidone, was synthesised by chemical oxidative polymerization of aniline in an acidic aqueous solution, and a novel class of polymer blends having electronically / ionically difunctional conductivities was prepared using solution blending of the PAn and an ion conducting polymer a complex (PEUU LiClO 4) of poly (ethylene glycol) type polyurethaneurea (PEUU) and LiClO 4. The polymer blend was studied by means of differential scanning calorimetry, dynamic viscoelastometer, stress strain test, four probe method and ac impedance spectroscopy. The results showed that the PAn and PEUU LiClO 4 were compatible, and the polymer blend had better overall properties.
