分别在盐酸和樟脑磺酸-盐酸混酸溶液中,在蒙脱土基新型氮掺杂多孔碳表面原位聚合苯胺,以制备氮掺杂多孔碳@聚苯胺复合电极材料,采用红外光谱(FTIR)、X射线衍射(XRD)和扫描电子显微镜(SEM)表征复合材料的组成和形貌。盐酸掺杂的复合材料呈短棒状形貌,樟脑磺酸-盐酸掺杂材料形貌呈颗粒状及交联片状,樟脑磺酸-盐酸掺杂的结晶性能优于盐酸掺杂。电化学测试结果表明,樟脑磺酸-盐酸掺杂的复合材料在0.5 A/g电流密度下的质量比电容为412.5 F/g,比盐酸掺杂的(332.4 F/g)高24.1%,等效串联电阻(Rs)和电荷迁移电阻(Rct)小;但盐酸掺杂的复合材料在大电流下电容保持率为81.4%,高于混酸掺杂的58.4%。

The composites of polyaniline ( PANI ) coating monthmorillonite-supported nitrogen-doped carbon ( NMC) were prepared by in situ polymerization of aniline upon NMC in the hydrochloric acid ( HCl) solution and the mixed acid solution composed of HCl acid and D-camphorsulfonic acid ( DCSA ) .Fourier transform infrared spectroscopy , X-ray diffraction , and scanning electron microscopy were employed to investigate the effect of the doping acid on the crystallization property .NMC@PANI doped with HCl has a short stick morphology , while one doped with HCl/DCSA exhibits a granular and flaked morphology and its crystallization degree is higher than that of the former .NMC@PANI doped with HCl/DCSA has a specific capacitance of 412.5 F/g at 0.5 A/g, which is increased by 24.1%compared to that of NMC@PANI doped with HCl, and shows a lower equivalent series resistance and charge transfer resistance . However , the capacitance of NMC@PANI doped with HCl retains 81.4% at large charge/discharge current , higher than 58.4% of one doped with HCl/DCSA.
