采用原位聚合法合成聚苯胺（PAIN）及聚苯胺/炭气凝胶（PAIN/CA）复合材料，经过高温裂解制备含氮碳（NC）及含氮碳/炭气凝胶复合材料（NC/CA），再以 KOH 为活化剂对其进行活化，制备活化含氮碳（ANC）及活化含氮碳/炭气凝胶复合材料（ANC/CA）。采用扫描电镜、循环伏安、恒流充放电以及电化学阻抗等方法进行性能测试，结果表明，由于 KOH 的活化作用，含氮碳材料的粒径明显变小，其比电容值为138 F/g，高于未活化含氮碳材料（98 F/g），ANC/AC3复合材料电极的比电容值比ACA电极（88 F/g）高，达到127 F/g。%Polyaniline (PANI) and polyaniline/carbon aerogels (PANI/CA) were synthesized by in situ polymerization, and pyrolyzed at high temperature to obtain nitrogen-containing carbon (NC) and nitrogen-containing carbon/carbon aerogels (NC/CA), then activated them with KOH as an activating agent. SEM, laser particle size analyzer, cyclic voltammetric experiments (CV), galvanostatic charge/discharge and electrochemical impedance spectroscopy (EIS) analysis was carried out in order to investigate their physical and electrochemical properties. The results showed that the particle diameters of activated nitrogen-containing carbon (ANC) became smaller owing to KOH activation, and its specific capacitance was 138 F/g, which was much higher than that of NC (98 F/g). The ANC/AC3 composites electrodes also exhibited higher specific capacitance of 127 F/g, in comparison with a value of 88 F/g for the ACA electrode.
