通过涂覆热分解法并结合电化学聚合法制备得到聚苯胺(PANI)/RuO2电极材料。使用涂覆热分解法于260℃热处理3h制备RuO2薄膜,通过电化学聚合法将PANI粒子沉积在RuO2薄膜上,并在80℃加热12h。采用XRD分析PANI/RuO2复合物晶相,采用SEM观察PANI/RuO2复合电极材料的形貌变化。利用循环伏安及恒流充放电测试了该复合电极的电化学性能。结果表明,PANI沉积时间为25min,该PANI/RuO2复合电极的最大电容量为9.72F,比电容为452F.g-1,充放电曲线体现了较低的电压降、等效串联电阻及良好的充放电性能。经1000次循环伏安后,其比电容损失约为11%。
Polyaniline (PANI) / RuO2 electrode materials were prepared by coating thermal decomposition and electrochemical polymerization. RuO2 thin films were prepared by thermal decomposition at 260 ℃ for 3h by coating thermal decomposition method. PANI particles were deposited on RuO2 films by electrochemical polymerization and heated at 80 ℃ for 12h. The crystal phase of PANI / RuO2 composite was analyzed by XRD. The morphology of PANI / RuO2 composite electrode was observed by SEM. The electrochemical performance of the composite electrode was tested by cyclic voltammetry and constant current charge-discharge test. The results show that the deposition time of PANI is 25min, the maximum capacity of PANI / RuO2 composite electrode is 9.72F and the specific capacitance is 452F.g-1. The charge-discharge curve shows a lower voltage drop, equivalent series resistance and good Charge and discharge performance. After 1000 cycles of voltammetry, the specific capacitance loss of about 11%.
