| 目的 设计一个低成本条件下成熟高效制备石墨烯-聚苯胺-银基复合电极材料的工艺路线。方法 研究石墨烯的制备工艺以及石墨烯与聚苯胺、银粒子的复合效果，将石墨烯与苯胺、银粒子通过原位聚合的方法制得石墨烯-聚苯胺-银复合材料。利用扫描电子显微镜(SEM)、傅里叶变换-红外光谱(FT-IR)、X射线衍射(XRD)、循环伏安法(CV)和恒电流充放电法(GCD)对石墨烯和石墨烯-聚苯胺-银复合材料的形貌、结构和电化学性能进行分析研究。结果 SEM、FT-IR、XRD等测试表明，聚苯胺类衍生物、石墨烯以及银粒子在整个复合材料中共存。结论 CV和GCD的测试结果表明复合材料有优良的电化学性能，比电容最高可达到293 F/g。 |
| 英文摘要: |
| The paper aims to design a mature and efficient process for preparing graphene-polyaniline-silver electrode composite materials at low cost. The preparation of graphene and the performance of graphene-polyaniline-silver composite materials were studied. The graphene, aniline and silver particles were prepared for the graphene-polyaniline-silver electrode composite materials by in-situ polymerization. The morphology, structure and electrochemical properties of graphene and graphene-polyaniline-silver composite materials were investigated via scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X ray diffraction (XRD), cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD). The SEM, FT-IR, XRD and other tests indicated that graphene, polyaniline derivatives and silver particles coexisted in the composite material. Test results of CV and GCD show that the composite materials have excellent electrochemical performance. The maximum specific capacitance could reach 293 F/g. |
