摘要


对化学氧化法制备导电聚合物聚吡咯的最优制备条件进行了摸索,通过万用表测试聚吡咯产物的电阻值,得到聚吡咯材料的导电性能.结果表明,表面活性剂的种类、氧化剂种类、聚合反应时间、聚合反应温度等对所制备的聚吡咯材料的导电性能有较大的影响.研究表明制备聚吡咯导电聚合物的最优条件是:使用苯磺酸钠为表面活性剂、FeCl3为氧化剂、吡咯单体与表面活性剂的物质的量比为3∶1、吡咯单体与FeCl3的物质的量比为1∶3,在冰水浴的实验条件(约为3~5℃)下,聚合反应12h. The optimal preparation conditions of chemical oxidative polymerization of polypyrrole were studied. To obtain the conductivity of polypyrrole material, the resistance of polypyrrole was tested by a multimeter. The results indicated that the factors influencing the conductivity of polypyrrole include the surfactant species, oxidants, polymerization time, polymerization temperature and so on. This study revealed that the optimal conditions for the synthesis of conductive polypyrrole were as follows: using benzene sulfonic acid sodium as the surfactant; FeCl3 as the oxidant; the molar ratio of pyrrole monomer to the surfactant was 3∶[KG-*3/5]1; the molar ratio of pyrrole monomer to FeCl3 was 1∶[KG-*3/5]3; and the controlled reaction in an ice-coldwater bathing (about 3—5 ℃ in Kunming) should last for 12 h.
