Preparation of Graphene Oxide/Fabric Electrode and Its Electrochemical Performance

随着电子设备朝小型化、柔性化及可穿戴化发展，超级电容器因其卓越性能在能源供应领域备受瞩目。本研究旨在探索氧化石墨烯(GO)与织物复合电极材料在超级电容器中的应用潜力。研究通过多种方法尝试将GO负载于织物，最终发现真空抽滤法可实现GO在织物表面的高覆盖量与牢固结合。在此基础上，以抗坏血酸为还原剂，控制不同还原时间制备复合电极材料并测试电化学性能。结果表明，还原时间显著影响性能，其中还原4小时的电极材料电化学性能最佳，对应器件面电容达142 mF∙cm−2且循环稳定性良好，为织物基柔性超级电容器发展提供重要参考，也为GO与织物复合电极材料研究提供了有价值的数据支持和工艺优化方向。With the development of electronic devices towards miniaturization, flexibility, and wearability, supercapacitors have attracted significant attention in the energy supply field due to their excellent performance. This study aims to explore the application potential of composite electrode materials of graphene oxide (GO) and fabric in supercapacitors. The study attempted to load GO onto the fabric through various methods and finally found that the vacuum filtration method can achieve high coverage and firm binding of GO on the fabric surface. On this basis, ascorbic acid was used as the reducing agent to prepare electrode with different reduction times, and their electrochemical properties were studied. The results show that the reduction time significantly affects the performance, and the electrode with a reduction time of 4 hours exhibits the best electrochemical performance. The corresponding device has an areal capacitance of 142 mF∙cm−2 and good cycling stability, providing an important reference for the development of fabric-based flexible supercapacitors and valuable data support and process optimization directions for the research of GO and fabric composite electrode.
