摘　　要：在低温(0℃)下化学氧化合成了盐酸掺杂聚吡咯(PPY),观察了聚合物的结构和形貌;用恒流充放电、循环伏安和交流阻抗法研究了聚合物的电化学电容性能。合成的PPY呈颗粒状,粒径约为0.2～0.3μm。当电流密度为8 mA/cm2时,PPY在1 mol/L Na2SO4溶液中的单电极比电容达350.2 F/g;当电流密度为10 mA/cm2时,第100次循环时的比电容为初始值的90.6%。Hydrochloride doped polypyrrole（PPY）was prepared by chemical oxidation at low temperature（0 ℃）,the structure and morphology of the polymer were observed.The electrochemical capacitive performance of the polymer was researched by galvano-static charge-discharge,cyclic voltammetry and AC impedance methods.The prepared PPY was grainy,the diameter was about 0.2～0.3 μm.The specific capacitance of the single electrode of PPY in 1 mol/L Na2SO4 solution was 350.2 F/g when the current density was 8 mA/cm2.The specific capacitance at the 100th cycle was 90.6% of the initial value when the current density was 10 mA/cm2.
