| 摘要: 首次提出了一种在离子液体中在石墨烯表面用恒电流法聚合3，4-乙烯二氧噻吩(EDOT)单体制备石墨烯/聚3，4-乙烯二氧噻吩(石墨烯/PEDOT)复合物的方法。用原子力显微镜、扫描电镜等技术表征证明石墨烯/PEDOT复合物是由PEDOT纳米谷粒状颗粒分散在石墨烯片表面而组成的。将该复合物用作超级电容器电极材料时，在1.0 A·g-1的充放电比电流下得到的比电容值为181 F·g-1。同时，该材料还显现出较好的充放电可逆性和稳定性。 |

| Abstract: A novel high-performance supercapacitor electrode material based on graphene/Poly(3,4-ethylenedioxythiophene) (G/PEDOT) hybrid was synthesized via in situ electropolymerization of the 3,4-ethylenedioxythiophene (EDOT) monomer on the graphene nanosheet in ionic liquid for the first time. The morphology characterization of the G/PEDOT hybrid by AFM and SEM demonstrated that the grain-shape PEDOT particles with the average size of 80 nm×40 nm×2 nm were attached to the graphene sheet′s surface tightly. The average specific capacitance of 181 F·g-1 of the hybrid was obtained in the potential range from 0 to 0.8 V at 1.0 A·g-1 by charge-discharge analysis and the hybrid showed good charge/discharge reversibility and electrochemical stability as supercapacitor electrode. |
