摘　　要：以纳米乙炔炭黑在盐酸掺杂的反应体系中的聚集体为硬模板,原位吸附化学氧化法制备了聚苯胺/炭黑复合材料。实验结果显示,聚苯胺复合物为表面附着大量纳米颗粒的类棒状结构,且棒与棒间富有孔隙。复合材料分解温度在350℃左右。循环伏安曲线表现出该复合材料法拉第准(赝)电容有良好的电极可逆性,在5,10 mA/cm2电流密度下,单电极比电容高达376 F/g和311 F/g。The polyaniline/carbon black composite was prepared by using the conductive carbon black as a template and by in situ chemical oxidization polymerization.The functional group,morphology and electrochemical properties of the composite were investigated.The results show that the morphology of the polyaniline/carbon black composite is assembled on which there are a mass of nano-particles.And there is much interspace among clubs.The decomposed temperatures of the composites are 350 ℃.The composite exhibits good reversibility for the electrode of redox capacitors and high specific capacitance that is as high as 376 F/g at 5 mA/cm2 and 311 F/g at 10 mA/cm2.
