中文摘要:
      文章研究了一种石墨烯复合电极材料制备方法,以低成本的纸纤维材料为柔性基板,结合双电层电容碳材料氧化石墨烯和赝电容导电聚合物聚苯胺的互补优势,通过超声分散和真空抽滤的方法,实现了纸纤维基-聚苯胺-还原氧化石墨烯复合电极材料的制备。采用场发射扫描电子显微镜、Zahner 电化学工作站对电极材料的循环伏安曲线、充放电性能进行测试分析。结果表明,柔性电极材料在 100 次弯曲测试后,没有发生明显分层和活性物质剥落现象,在电流密度为 1 A/g 时比电容为 458 F/g,10 A/g 电 流密度下比电容为 250 F/g,经过 1 000 次充放电循环后,比电容仍能保持 80% 左右。这种高性能低成本的柔性复合电极材料在可穿戴式电子设备领域具有广阔的应用前景。
英文摘要:
      A flexible paper fiber-reduced graphene oxide-polyaniline hybrid electrode was investigated in this article. Using low-cost paper fiber as flexible substrate, the electrode was prepared through ultrasonic dispersion and vacuum filtration. It combined the advantages of graphene oxide electric double layer with polyaniline conductive polymer pseudo-capacitance. The obtained electrode was characterized and tested by various instrumentations such as scanning electron microscope, cyclic voltammetry and galvanostatic chargedischarge. In the bending test experiments, the obtained electrode was not separated into individual layers after hundreds of bending cycles. The flexible paper fiber-reduced graphene oxide-polyaniline hybrid electrode also exhibits excellent capacitance (458 F/g at a discharge current density of 1 A/g and 250 F/g at a discharge current density of 10 A/g) and remarkable cycling stability with capacitance degradation about 20% after 1 000 charge-discharge cycles at a current density of 3 A/g. The proposed flexible electrode has great potentials in the development of flexible energy-storage devices for wearable electronic products.
