摘要: 以对苯二腈、氧化石墨烯(GO)为原料,通过简单离子热的方法合成三嗪基共价有机骨架/石墨烯(CTFs/G)复合材料,并将其用作超级电容器电极材料,通过电化学工作站对其电化学性能进行了分析.结果表明:CTFs/G复合材料具有较好的倍率特性,表现出优良的电化学性能,在0.2 A/g的电流密度下,其比电容可以达到372 F/g,高于CTFs材料的166 F/g,经1000次循环后其比电容仍维持在168 F/g,循环稳定性较好.Abstract: With phthalonitrile,graphene oxide(GO) as raw material,triazine-linked covalent organic framework/graphene composite was synthesized by a simple ion thermal method.As supercapacitor electrode material,the electrochemical performance of the CTFs/G composites was analyzed by electrochemical workstation. The results showed that the CTFs/G composites had good rate capability and excellent electrochemical performance.The composites displayed specific capacitance of 372 F/g at current density of 0.2 A/g,which is much higher than that of pure CTFs (166 F/g).It could be remained at 168 F/g after 1000 cycles,and the cycle stablity was good.
