In this study, a quite simple method has been represented for the fabrication of polymeric crosslinked graphene nanocomposite and examined for supercapacitance properties. Since most of the azo dyes display the conjugated structures, their contribution to enhance the conductivity and capacitance of carbon containing compounds such as graphene could be an interesting area. Therefore, in the present work, chrysoidine (CHRYS) was polymerized in the presence of graphene oxide (GO) in which the produced polychrysoidine (PCHRYS) acted as a cross linker for GO nanosheets. The optimized components ratio of GO:PCHRYS forms the efficient porous graphene oxide-polychrysoidine (GO-PCHRYS) nanocomposite which easily stores charge and represents a rather high specific capacitance of 715.3 F g−1 at the current density of 0.5 A g−1. The electrode stability was determined after 10000 cycles via comparing initial and final capacitance and the results indicated that 89.8% of the initial capacitance had been maintained .

超级电容器应用中氧化石墨烯-聚甲基吡啶纳米复合材料的合成

在这项研究中,已经提出了一种非常简单的方法来制备聚合物交联石墨烯纳米复合材料,并检查了其超电容性能。由于大多数偶氮染料都具有共轭结构,因此它们对增强含碳化合物(如石墨烯)的电导率和电容的贡献可能是一个有趣的领域。因此,在目前的工作中,在氧化石墨烯(GO)存在下聚合了菊苣苷(CHRYS),其中产生的聚胆苷(PCHRYS)充当了GO纳米片的交联剂。GO:PCHRYS的最佳成分比形成有效的多孔氧化石墨烯-聚氧化亚丁(GO-PCHRYS)纳米复合材料,该复合材料易于存储电荷,并具有715.3 F g -1的相当高的比电容在0.5 A g -1的电流密度下。10000次循环后,通过比较初始和最终电容来确定电极的稳定性,结果表明初始电容已保持89.8%。
