摘要
可穿戴电子设备的快速发展推动了人们对柔性超级电容器的研究。导电聚合物由于其高导电性、快速可逆的氧化还原反应及类似传统聚合物材料的柔韧性,在柔性超级电容器中具有巨大的应用潜力。纯导电聚合物电极电化学性能有限(低循环寿命和实际容量),与新兴的二维材料组成复合材料能改善其电化学性能。本文首先介绍了二维材料与导电聚合物复合材料从一维到三维的制备与组装策略,随后综述了它们在不同结构(纤维结构、三明治结构和平面叉指结构)柔性超级电容器中的最新研究进展,最后指出了导电聚合物基复合材料在柔性超级电容器中面临的挑战以及未来的发展趋势。
The rapid development of wearable electronic devices has promoted the research of flexible supercapacitors.Conducting polymers have shown great application potential in flexible supercapacitors due to their high conductivity,fast and reversible redox reaction,and flexibility similar to traditional polymer materials.Pure conducting polymers electrodes exhibit limited electrochemical performance(short cycling life and low actual capacity),and the formation of composite materials with emerging two-dimensional materials can improve their electrochemical performance.The preparation and assembly strategies of two-dimensional materials(graphene,transition metal chalcogenides,and transition metal carbon/nitride)composites from one to three dimensions is discussed firstly,and then the latest progress in their application in flexible supercapacitors with different structures(fiber structure,sandwich structure and planar interdigital structure)is reviewed.Finally,the challenges and future development trend of conducting polymer matrix composites in flexible supercapacitors are presented.
