摘　　要：以钨酸钠、石墨和苯胺为主要原料,采用水热合成法和原位聚合法制备GO/WO_3/PANI三元复合材料,对其电化学性能进行测试.结果表明:三元材料的复合可以提高材料的综合电化学性能,在20 m V/s的扫描速率下、纳米WO_3的添加量为0. 42 g时,三元复合材料样品GWP-4的电化学性能最好;随着充放电电流的增大,该样品的放电时间缩短,比电容减小,在充放电电流为0. 2 A/g时,其比电容最大,为107 F/g.The GO/WO3/PANI ternary composites were prepared by hydrothermal synthesis and in situ polymerization using sodium tungstate as the main raw material.The electrochemical properties were tested.The results showed that the composite of ternary materials could improve the overall electrochemical performance of the material.At the scanning rate of20mv/s,the addition of nano-WO3was0.42g,and the electrochemical performance of ternary composites sample GWP-4was the best;as the charge and discharge current increased,the discharge time of the sample was shortened,and the specific capacitance was reduced.When the charge and discharge current was0.2A/g,the specific capacitance was the largest,which was107F/g.
