摘要
本文以过硫酸铵为引发剂,植酸为掺杂酸,在溶液中原位聚合合成了碳纳米管(CNTs)/苯乙烯-丁二烯-苯乙烯(SBS)/聚苯胺(PANI)复合电极材料。通过红外光谱(IR)、扫描电镜(SEM)对电极材料的结构和微观形貌进行了表征。通过循环伏安法(CV)、交流阻抗谱(EIS)、恒电流充放电(GCD)等电化学手段对材料的电化学性能进行了表征。结果表明:与SBS/PANI复合材料相比,CNTs/SBS/PANI复合电极材料具有更高的比电容、循环稳定性和倍率性能。当CNTs的加入量占苯胺单体质量百分比为3%,在扫描速率为5 mV/s时,CNTs/SBS/PANI复合电极材料的比电容最大为356.7 F/g。
Abstract
Carbon nanotubes(CNTs)/styrene butadiene styrene(SBS)/polyaniline(PANI) composite electrode materials were synthesized by in-situ polymerization in solution with ammonium persulfate as initiator and phytic acid as doping acid. The structure and morphology of the electrode materials were characterized by IR and SEM. The electrochemical properties of the materials were characterized by CV, EIS and GCD. The results show that CNTs/SBS/PANI composite electrode materials have higher specific capacitance, cycle stability and rate performance than SBS/PANI composites. The maximum specific capacitance of CNTs/SBS/PANI composite electrode material is 356.7 F/g when the content of CNTs in aniline monomer is 3% and the scanning rate is 5 mV/s.
