Preparation and performance of zinc@polypyrrole fabric electrode

  • 摘要: 为满足可穿戴智能纺织品微电子功能元件的供能需求,柔性储能器件成为研究的重点。电极是储能器件重要组成部分,决定了器件能量存储的大小。本文以导电镀银锦纶织物为基体,采用磁控溅射技术将金属锌(Zn)负载在织物表面,再通过化学聚合和电化学聚合两种方式构筑导电高分子聚吡咯(PPy)。分别对Zn@PPy/织物电极的表观形貌、电学性能和电化学性能进行评价,并探究化学聚合和电化学聚合PPy及磁控溅射时间对织物电极性能的影响。结果表明:采用磁控溅射镀技术可在织物表面实现Zn膜的均匀生长,表面方阻为1.51 Ω;制备的Zn@PPy/织物电极比电容高达1185 mF/cm2,是PPy/织物电极的4.21倍。该织物电极制备方法简单,在可穿戴纺织品微电子供能领域具有潜在的应用前景。
