The well-defined core-shell carbon black/polypyrrole (CB/PPy) nanocomposites were prepared via the in situ chemical oxidative polymerization of pyrrole from the surfaces of the carbon black (CB) nanoparticles, with poly(2-hydroxy-3-(methacryloyloxy) propane-1-sulfonate) (PHMAS) as both the surfactant and the dopant. The nanocomposites exhibited the high conductivity at room temperature and the weakly temperature dependence of conductivity from 283 to 423 K. When the core-shell CB/PPy nanocomposites were used as the electrode materials for the supercapacitors, the maximum discharge capacity of 366 F/g was achieved, after being corrected for the weight percentage of the PPy phase at the current density of 5 mA/cm(2) in 1.0 M NaNO(3) electrolyte solution.
采用聚（2-羟基-3-（甲基丙烯酰氧基）丙烷-1-磺酸）（PHMAS）同时作为表面活性剂和掺杂剂，通过在碳黑（CB）纳米粒子表面原位化学氧化聚合吡咯，制备了具有明确核壳结构的碳黑/聚吡咯（CB/PPy）纳米复合材料。该纳米复合材料在室温下表现出较高的电导率，且电导率在 283 到 423 K 之间具有较弱的温度依赖性。当核壳 CB/PPy 纳米复合材料用作超级电容器的电极材料时，在 1.0 M NaNO3 电解质溶液中，电流密度为 5 mA/cm2 时，经过对 PPy 相的重量百分比进行修正，其最大放电容量达到了 366 F/g。
