摘要本文将氮掺杂多孔碳（NPC）作为基体，通过化学原位聚合法制得了NPC/聚苯胺（PANI）复合材料，并运用傅里叶变换红外、X射线衍射和扫描电子显微镜等技术表征了其在不同类型酸和表面活性剂存在下的形貌，同时对其电化学性能进行了研究。结果表明：An和NPC质量比为3:1时，HCl掺杂NPC/PANI的比电容达到最高值，为332.4F·g-1；D-樟脑磺酸（DCSA）和HCl浓度比为1:4时，DCSA/HCl共掺杂NPC/PANI的比电容为412.5F·g-1，高于HCl单独掺杂时的比电容；表面活性剂SDS加入后，使得DCSA/HCl共掺杂NPC/PANI的比电容降至368.2F·g-1，但是其在大电流下的比电容保持率较高，故而具有优良的电化学性能。48042

Abstract
In this paper, NPC/polyaniline (PANI) composite materials were prepared by chemical in-situ polymerization method in the presence of nitrogen-doped porous carbon(NPC) as a substrate. The structure and morphology of NPC/PANI composite materials under the participation of different types of acids and surfactants were characterized by Fourier Transform Infrared, X-ray diffraction and scanning electron microscopy techniques, while its electrochemical properties were studied. The results indicated: When the mass ratio of An and NPC is 2.4:1, the HCl doped NPC/PANI composite material shows the highest specific capacitance of 332.4 F·g-1; when the concentration ratio of D- camphor sulfonic acid (DCSA) and HCl is 1:4, the specific capacitance of DCSA/HCl co-doped NPC/PANI composite is up to 412.5F·g-1 and higher capacity compared with the HCl doped NPC/PANI composite; after SDS surfactant is added, the specific capacitance of DCSA/HCl co-doped NPC/PANI composite material dropped to 368.2F·g-1, but its specific capacitance retention is relatively high at big current density, therefore it has good electrochemistry performance.
