摘 要:利用化学氧化法原位聚合制备了聚苯胺(PANI)/氧化石墨烯(GO)接枝复合材料。透射电子显微镜表明,PANI纳米颗粒均匀地分布在GO的表面;通过UV-vis光谱证实了GO和PANI之间存在着强烈的相互作用;充放电测试表明,PANI/GO纳米复合材料具有良好的电荷储存特性,最高比电容可达575 F/g。由于与GO之间的化学结合作用,PANI的充放电循环稳定性得到明显提高。 |

Abstract:The polyaniline(PANI)/graphene oxide(GO)grafted composites were prepared by in-situ oxidized polymerization. The PANI particles were homogeneously distributed on the surface of GO detected by TEM. The strong interaction between GO and PANI was proved by UV-vis analysis. The PANI/GO composite showed good charge-storage behaviors by the charge-discharge test. The highest specific capacitance of 575 F/g was obtained, and the cyclability of PANI was greatly enhanced because of the covalent bonds between PANI and GO. |
Key words:chemically oxidized method; in-situ polymerization; polyaniline; graphene oxide |
