摘要
聚苯胺(PANI)具有高导电率、高比电容、快速的掺杂-脱掺杂能力和原料经济易得等特性,但是作为电极材料进行循环充放电时易发生材料的形变,循环稳定性差。三维(3D)石墨烯具有比表面积大、电子迁移速率高、透光性和柔韧性好、机械性能稳定等特点。将两者进行三维结构设计以提高复合材料的电化学性能是目前研究的热点。介绍了3D石墨烯材料的制备方法,并综述了3D石墨烯-聚苯胺复合材料的制备方法及在超级电容器电极材料中的应用现状,对其存在的问题和未来发展方向进行了展望。
Polyaniline（PANI）is the most widely used conducting polymer material for supercapacitors due to its distinctive features such as high conductivity,excellent capacity for energy storage,fast capacity of doping-de doping and low cost.However,due to its drawbacks of swelling and shrink age during the doping-de doping processes,PANI is susceptible to a rapid degradation in electrochemical performance upon repetitive cycles of charge-discharge,resulting in a poor cycling stability.Three dimensional（3D）graphene has the characteristics of high specific surface area,fast mass and electron transport,good light transmittance,good flexibility,and stable mechanical properties.In order to overcome these limitations,much attention has been devoted to preparing three dimensional（3D）composite by combining PANI with graphene.The preparation of 3Dgraphene-based nanomaterials were presented.The preparation status of 3Dgraphene/polyaniline composite in supercapacitor were summarized in details.Finally,the development tendency of 3Dgraphene/polyaniline materials was predicted.
