中文摘要：
以脲醛树脂（UF）为前驱体,经高温碳化和氢氧化钾溶液活化处理,制备脲醛树脂多孔碳（UFC）,采用原位化学聚合法制备聚吡咯（PPy）/UFC复合材料。通过SEM、XRD和红外光谱等分析复合材料的形貌和结构特征;采用循环伏安、电化学阻抗和恒流充放电测试复合材料的电化学性能。PPy/UFC复合材料比单独的PPy和UFC具有更高的比表面积和更好的电化学性能,以4 A/g在-1.0-0 V循环,比电容为545 F/g,循环2 000次的电容保持率为91%。
英文摘要：
Urea-formaldehyde resin （UF） derived porous carbon （UFC）was prepared by using UF as the precursor and activated with KOH solution. Polypyrrole（Ppy）/UFC composite was further prepared by in-situ chemical polymerization. The nanoeomposite was analyzed by SEM, XRD, Fourier-transform infraredspeetra（FTIR）. The electrochemical performance of the nanocomposite was tested by cyclic voltammetry, electrochemical impedance spectroscopy （EIS）and galvanostatie charge-discharge. The Ppy/UFC composite had higher specific surface area and better electrochemical performance than single Ppy and UFC. When cycled in - 1.0 -0 V with 4 A/g,its specific capacitance was 545 F/S,the capacitance retention rate was 91% after 2 000 cycles.
