摘要
聚苯胺制备工艺简单,价格低廉,结构稳定,理论比容量大,掺杂过程简单,具备掺杂和反掺杂的性能,但循环稳定性差,将其与石墨烯复合,利用二者的协同作用能够更好地提高电容性能。与二维石墨烯相比,三维石墨烯具有独特的三维多孔结构,不仅增加了与电解液的接触面积,同时提供了快速的电子传输通道,而且其独特的网状结构可减少聚苯胺在复合材料中的团聚使其在超级电容器方面表现出良好的潜力。介绍了三维石墨烯的制备方法,主要包括自组装法和模板导向法;综述了三维石墨烯/聚苯胺复合材料以及掺杂改进的三维石墨烯/聚苯胺复合材料的制备方法及其电化学性能在超级电容器中的研究进展;并对其未来研究发展趋势进行了展望。
Polyaniline preparation process is simple with low costs,the structure is stable,the theoretical specific capacity is large,and easy to dope and anti-dope.However,the cycle stability of polyaniline is weak.It is effective to improve the electrochemical performance by compositing with graphene due to the synergistic effect of both.Compared with the two-dimensional graphene,the three-dimensional graphene has the unique three-dimensional porous structure,it will increase the contact area with the electrolyte and provide fast electron transport channels.And the unique network structure can reduce the agglomeration of polyaniline in the composites,tand makes it have a good potential for supercapacitors.The preparation methods of3D graphene including self-assembly and template methods were introduced.The preparation methods of three-dimensional graphene/polyaniline composites and the improved three-dimensional graphene/polyaniline composites and their electrochemical performance in supercapacitors were reviewed.The future development trend of the three-dimensional graphene/polyaniline composites was also predicted.
