通过热还原法成功地制备出了柔性复合织物电极石墨烯/棉布(graphene/cotton)。热还原条件对电极的导电性能具有较大的影响。导电柔性织物电极graphene/cotton特有的多级结构使其既有利于进一步负载膺电容材料,又有利于电子和电解质离子的传输与扩散。通过电化学沉积方法,利用导电柔性织物电极graphene/cotton进一步制备出了电极MnO_2/graphene/cotton。利用扫描电子显微镜(SEM),傅里叶变换红外(FTIR)光谱,四探针测试法等表征技术对电极的结构进行了较为详细的表征。结果表明电极MnO_2/graphene/cotton的比电容可以达到536 F?g~(-1)。良好的电化学性能和柔性使得此类电极在柔性储能材料应用中具有极大的应用前景。
The flexible composite fabric electrode graphene / cotton was successfully prepared by thermal reduction method. Thermal reduction conditions have a greater impact on the conductivity of the electrode. Conductive flexible fabric electrode graphene / cotton unique multi-level structure makes it both conducive to further charge Ying capacitive materials, but also conducive to the transport and diffusion of electronic and electrolyte ions. The electrode MnO 2 / graphene / cotton was further prepared by electrochemical deposition method using graphene / cotton as conductive flexible fabric. The structure of the electrode was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and four-probe method. The results show that the specific capacitance of MnO 2 / graphene / cotton electrode can reach 536 F? G -1. Good electrochemical performance and flexibility make these electrodes have great application prospects in the application of flexible energy storage materials.
