Abstract

An effective approach for the large-scale fabrication of conducting polyaniline (PANI) using in situ anodic electrochemical polymerization on nickel foam which had been coated in aryl diazonium salt (ADS)-modified graphene (ADS-G). In the present work, ADS-G was used as a high surface-area support material for the electrochemical polymerization of PANI. The electrochemical performances of the ADS-G/PANI composites exhibited better suitability as supercapacitor electrode materials than those of the PANI. The ADS-G/PANI composites achieved a specific capacitance of 528 F g, which was higher than that of PANI (266 F g) due to excellent electrode-electrolyte interaction and the synergistic effect of electrical conductivity between ADS-G and PANI in the composites. These findings suggest that the ADS-G/PANI composites are a suitable composite for potential supercapacitor applications.

摘要

一种在涂覆有芳基重氮盐（ADS）修饰的石墨烯（ADS-G）的泡沫镍上通过原位阳极电化学聚合大规模制备导电聚苯胺（PANI）的有效方法。在本工作中，ADS-G用作PANI电化学聚合的高比表面积支撑材料。ADS-G/PANI复合材料的电化学性能作为超级电容器电极材料表现出比PANI更好的适用性。ADS-G/PANI复合材料实现了528 F/g的比电容，由于复合材料中优异的电极-电解质相互作用以及ADS-G和PANI之间电导率的协同效应，该比电容高于PANI的比电容（266 F/g）。这些发现表明ADS-G/PANI复合材料是适用于潜在超级电容器应用的复合材料。
