摘要:
先通过软模板法制备具有纳米管状结构的聚吡咯（PPy），再以此PPy与氧化石墨烯（GO）为前驱物，通过水热法制备具有三维结构的聚吡咯/石墨烯（PG）复合水凝胶。研究了PPy用量对复合水凝胶的影响。利用扫描电子显微镜对其形貌进行表征，用循环伏安法和恒电流充放电法对复合凝胶的电化学性能进行了研究。结果表明，当m（PPy）∶m（GO）在1.5∶1到2.5∶1之间时，可以形成完整的PG复合水凝胶，复合水凝胶可承受自身重量约1 000倍的压力。PG复合水凝胶具有良好的电化学性能，当恒电流充放电测试的电流密度增加到20 A/g时，复合水凝胶的比电容仍然大于400 F/g。这些结果表明PG复合水凝胶在超级电容器领域有着较好的应用前景。
Abstract:
To fabricate polypyrrole/graphene（PG） composite with three-dimensional network，polypyrrole（PPy） nanotubes prepared by soft template and graphene oxide（GO） were used as precursors，then PG composite hydrogels were synthesized by hydrothermal method. The effects of the amount of PPy on the fabrication of composited hydrogel were studied. The morphology of the composite hydrogels were characterized by scanning electron microscopy，and its electrochemical properties were investigated by cyclic voltammetry and galvanostatic charge-discharge tests. When the mass ratio of PPy to GO was in the range of 1.5∶1 to 2.5∶1，the regular PG composite hydrogels were obtained which could hold a stuff as high as about 1 000 times of its own weight，and also showed excellent electrochemical performance with more than 400 F/g of specific capacitance at 20 A/g of current density in the galvanostatic charge-discharge test. The results indicated that the PG composite hydrogels might be promising material in the application of supercapacitor electrode.
