以全棉机织布和全棉水刺非织布作为柔性基材,通过化学氧化法制备超级电容器用聚吡咯/棉织物复合电极材料.研究电极材料样品的电学性能,测试结果表明,电极材料样品具有良好的电学性能,在0.1 A/g电流密度下,聚吡咯/棉机织布和聚吡咯/棉非织布电极材料样品的比容量分别为346 F/g和282 F/g.以两种电极材料样品分别与PVAH_3PO_4凝胶电解质组装柔性固态超级电容器,进行电化学性能测试,在电流密度为1 mA cm^(-2)时,基于聚吡咯/棉机织布和聚吡咯/棉非织布电极材料组装的固态超级电容器容量为0.64 F/cm^2(152.2 F/g)和0.44 F/cm^2(115.7 F/g).
mPolypyrrole / cotton composite electrode material for supercapacitor was prepared by chemicaloxidation method using cotton woven fabric and cotton spunlace non-woven fabric as flexible substrate. Theelectrical properties of electrode material samples were studied. The results showed that the electrode materialsamples had good electrical properties and capacitor characteristics. The specific capacity of polypyrrole / cottonfabric and polypyrrole / cotton nonwoven electrode material sample is 346 F / g and 282 F / g respectively at acurrent density of 0. 1 A/ g. A flexible solid state supercapacitor was assembled with the PVA-H3PO4 gelelectrolyte respectively with two samples of the electrode material. The same electrochemical performance testwas carried out on the sample of the capacitor. When the current density was 1 mA·cm - 2, the surfacecapacitance of the solid state supercapacitor assembled with the polypyrrole / cotton woven fabric electrodematerials and polypyrrole / cotton nonwoven fabric electrode materials was 0. 64 F / cm2(152. 2 F / g) and 0. 44F / cm2(115. 7 F / g).
