通过同步还原聚苯胺(PANI)-氧化石墨烯(GO)复合物制备得到了聚苯胺-还原氧化石墨烯(PANI-rGO)。由于复合材料中PANI提供了氧化还原反应的电荷,使得PANI-rGO复合材料具有较大的比电容。通过扫描电子显微镜(SEM),紫外-可见光谱和热重量分析法(TGA)对复合物进行了结构和形态的分析。复合材料的形态呈薄片状,聚苯胺是均匀地包裹在氧化石墨烯上的。当电流密度为20 A·g~(-1)时,PANI-rGO复合材料的比电容可高达1069 F·g~(-1)(1.71 F·cm~(-2)),是PANI-GO复合材料的五倍,这是因为复合材料中还原氧化化石墨烯的大比表面和高电导性所引起的。
Polyaniline-reduced graphene oxide (PANI-rGO) was prepared by simultaneous reduction of polyaniline (PANI) -sized graphene oxide (GO) composite. PANI-rGO composites have larger specific capacitance due to the redox reaction of PANI in the composite. The structure and morphology of the composites were analyzed by scanning electron microscopy (SEM), UV-vis spectroscopy and thermogravimetric analysis (TGA). The morphology of the composite material was flaky, and polyaniline was uniformly coated on the graphene oxide. When the current density is 20 A · g -1, the specific capacitance of PANI-rGO composites can reach as high as 1069 F · g -1 (1.71 F · cm -2) Five times as much as the composite, due to the large specific surface area and high electrical conductivity of the reduced oxidized graphene in the composite.
