摘要：

为使石墨烯与织物更好地结合制备可折叠、电化学性能良好的柔性超级电容器,以乙醇和N,N-二甲基甲酰胺作为溶剂,鳞片石墨为溶质,通过液相剥离法制备石墨烯溶液,再采用电化学沉积法将石墨烯负载到棉针织物表面。借助场发射扫描电子显微镜和傅里叶变换红外光谱仪对棉针织物及柔性电极的表面形貌、元素含量及结构进行表征。结果表明:织物表面负载的石墨烯层数较少,且团聚现象不明显,采用电化学沉积法可成功地将石墨烯负载在棉织物上;当电沉积时间为90 min时,石墨烯-棉针织物电极材料的比电容为464.3 F/g,等效串联电阻为10.45 Ω,表现出良好的电容性、导电性、循环性能和柔韧性。

Abstract:

In order to achieve better combination of graphene and fabric, flexible supercapacitors with foldable and good electrochemical properties were prepared, using ethanol and N, N-dimethylformamide as solvents and the flake graphite as a solute. Graphene solution was prepared by liquid phase stripping method, and graphene was loaded onto knitted fabric surface by electrochemical deposition method. The surface morphology, content and composition of the knitted fabric and the flexible electrode were analyzed by scanning electron microscopy and Fourier transform infrared spectrometry. Research results indicate that the number of graphene layers loaded on the surface of the fabric is smaller, the agglomeration is not obvious, and the graphene is loaded on the fabric successfully by electrochemical deposition. When the electrodeposition time is 90 min, the specific capacitance of graphene-fabric electrode material is 464.3 F/g, and the equivalent series resistance is 10.45 Ω, showing good capacitance, conductivity, cycle performance and flexibility.

Key words: graphene, flexible electrode material, liquid-phase stripping, electrochemical deposition
