Description
技术领域Technical field
本发明涉及一种用于超级电容器的碳纳米管-聚苯胺复合材料的制备方法。The invention relates to a preparation method of a carbon nanotube-polyaniline composite material used for a supercapacitor.
背景技术 Background technique
电化学电容器由于具有广泛的应用前景和巨大的潜在市场而成为国际能源领域的研究热点。碳纳米管(CNTs)由于具有高导电性、高中孔含量、无“死孔”、良好的电化学稳定性而成为电化学电容器的理想电极材料。但由于碳纳米管的比表面积比较低，致使其比容也较低。碳纳米管的低比容问题已成为制约其作为超级电容器电极材料的瓶颈。Electrochemical capacitors have become a research hotspot in the international energy field because of their broad application prospects and huge potential markets. Carbon nanotubes (CNTs) are ideal electrode materials for electrochemical capacitors due to their high electrical conductivity, high and medium pore content, no "dead pores", and good electrochemical stability. However, due to the relatively low specific surface area of carbon nanotubes, their specific volume is also low. The low specific volume of carbon nanotubes has become a bottleneck restricting their use as electrode materials for supercapacitors.
