摘要:
为了得到新型导电聚合物/石墨烯纳米复合材料, 采用偶氮染料甲基橙为掺杂剂，过硫酸铵为氧化剂，一步法制备了纳米片状的聚吡咯/氧化石墨烯复合材料，通过傅里叶红外光谱、扫描电子显微镜等测试, 对聚吡咯/氧化石墨烯复合材料的结构和形貌进行表征; 通过循环伏安法对其进行电化学性能测试.结果表明：由于甲基橙分子中含有的磺酸根阴离子, 甲基橙分子掺杂在聚吡咯分子链中，影响了聚吡咯分子的共轭结构；在聚吡咯/氧化石墨烯复合材料中保留了氧化石墨烯的片状结构，表明吡咯单体首先被吸附到氧化石墨表面，进而在氧化石墨烯表面发生聚合.聚吡咯/氧化石墨烯复合材料均匀的片状纳米结构，在循环伏安测试中显现出具有良好的电容特性，将来可以应用到商业电容器领域.
Abstract:
To obtain the composites of conducting polymer and grapheme, methyl orange was used as the dopant and ammonium persulfate was used as the oxidant to prepare polypyrrole/graphene oxide nanocomposites. Fourier transform infrared spectroscopy, scanning electrom microscope and electrochemical experiments were carried out to characterize the structure, morphology and electrochemical properties of the composites. The results show that methyl orange affects the conjugated structure of polypyrrole after it is doped in the molecular chains of polypyrrole; the nanosheets of graphene oxide are retained in the nanocomposites, which indicates that pyrrole monomer is firstly absorbed on the surface of the graphene oxide nanosheets and then polymerized. Polypyrrole/graphene oxide composite has good electrochemical properties with their uniform nanosheet structure, which will be used as supercapacitors in the future.
