摘要:本文通过静电纺丝技术制备出电导率良好的自支撑碳纳米纤维网络(CNFs)作为电极内部的集流器,并在室温下采用重复化学原位聚合法在CNFs表面均匀沉积一层聚苯胺(PANI)聚合物,成功制备出一维3D的CNFs/PANI独立复合电极。采用扫描电子显微镜和X射线衍射仪对样品形貌和组成成分进行详细分析。在三电极体系下,CNFs/PANI复合电极的比电容达到了412 F/g,在经过5000次充放电循环后比电容仍保持初始比电容81%。
Abstract:In this paper, the self-supported carbon nanofiber networks (CNFs) with good electrical conductivity were prepared by electrospinning as the collector inside the electrode, and a layer of polyaniline (PANI) polymer was uniformly deposited on the surface of CNFs by repeated chemical in situ polymerization at room temperature, and the one-dimensional 3D CNFs/PANI independent composite electrode was successfully prepared. The sample morphology and composition were analyzed in detail by scanning electron microscopy and X-ray diffractometer. In the three-electrode system, the specific capacitance of CNFs/PANI composite electrode reached 41 F/g, and the initial specific capacitance remained 81% after 5000 charge and discharge cycles.
