摘　　要：以植酸为掺杂酸和凝胶剂,过硫酸铵为引发剂,采用原位聚合法制备了CNTs/PANI复合水凝胶电极材料。通过红外光谱、扫描电镜对制备材料的结构和微观形貌进行了表征。通过循环伏安法、交流阻抗谱、恒电流充放电等电化学手段对材料的电化学性能进行了表征。结果表明:碳纳米管的引入极大地提高了复合水凝胶的比电容值;适当增加植酸用量,有利于提高复合水凝胶的电荷储存能力。CNTs/PANI composite hydrogel electrode materials were prepared by in-situ polymerization using phytic acid as doping acid and gel agent,ammonium persulfate as initiator.The structure and micromorphology of the prepared materials were characterized by FT-IR and SEM.The electrochemical properties of the materials were characterized by CV,EIS and GCD.The results show that:the specific capacitance of the composite hydrogel is greatly improved by the introduction of carbon nanotubes;proper addition of phytic acid is beneficial to enhancing the charge storage capacity of composite hydrogels.
