摘要
采用冷冻干燥后管式炉碳化制备壳聚糖电极材料,经KOH活化法活化后通过氧化还原聚合法制备聚苯胺(PANI)/壳聚糖电极材料,运用循环伏安、交流阻抗、充放电等测试聚苯胺/壳聚糖电极的电化学性能。结果表明,聚苯胺/壳聚糖电极材料表现出良好的电容性能和稳定的电化学性能,比电容129.6F/g,循环充放电500次,比电容保持率90.8%。
Chitosan electrode materials were prepared by freeze drying and carbonization in tubular furnace.After activation by KOH,chitosan (PANI)/polyaniline electrode materials were prepared by oxidation-reduction polymerization.The electrochemical properties of chitosan/polyaniline electrodes were tested by cyclic voltammetry,alternating current impedance,etc.Chitosan/polyaniline electrode materials show good capacitance and stable electrochemical properties.The specific capacitance is up to 129.6 F/g,and the specific capacitance retention rate reaches 90.8% after 500 cycles of charging and discharging.
