以过硫酸铵为氧化剂,对甲基苯磺酸钠为掺杂剂,PVA为改性剂采用化学氧化法制备了聚吡咯(PPy)/PVA复合材料。用红外光谱、拉曼光谱以及扫描电镜等表征手段对比研究了复合材料与单一聚吡咯产物结构和形貌变化,研究了复合材料的电化学性能,实验结果表明,PVA的加入对聚吡咯的性能改善有一定的影响,PVA添加量为0.5g时复合材料有较大的电导率,经循环伏安和充放电测试表明,复合材料具有较好的电化学性能。
Using ammonium persulfate as oxidant and sodium p-toluenesulfonate as dopant, polypyrrole (PPy) / PVA composites were prepared by chemical oxidation using PVA as modifier. The structure and morphology of the composite and single polypyrrole were investigated by means of FTIR, Raman spectroscopy and scanning electron microscopy. The electrochemical properties of the composite were investigated. The experimental results show that the properties of polypyrrole Improve the impact of a certain amount of PVA 0.5g composite materials have greater electrical conductivity, cyclic voltammetry and charge-discharge test showed that the composite has good electrochemical properties.
