目前，开发新型、廉价、高性能的柔性储能电极材料已成为研究热点。有机染料被认为是最常见的水污染来源之一，其排放不仅破坏了生态平衡，而且浪费了大量宝贵的化工原料。具有固有氧化还原官能团的蒽醌衍生物和吩噻嗪染料可通过简便的恒流聚合法从废水中有效去除，并可作为电化学储能材料加以利用。在此基础上，成功制备了一种基于染料分子的新型柔性超级电容器，并表现出优异的电化学性能，为同时处理废水和制备功能器件提供了一种明智的策略。
Currently, the development of novel, cheap and high-performance electrode materials for flexible energy-storage devices is being intensively pursued. Organic dyes are regarded as one of the most common water pollution sources, and their discharge not only damages the ecological balance but also wastes a lot of valuable chemical raw materials. With intrinsic redox functional groups, two types of widely used dyes including anthraquinone derivatives and phenothiazine dyes can be effectively removed from their effluent by a facile galvanostatic polymerization method, and resource utilized as electrochemical energy-storage materials. Based on this, a new kind of flexible supercapacitor based on dye molecules has been successfully fabricated, and exhibits excellent electrochemical performance, demonstrating a wise strategy for simultaneous wastewater treatment and preparation of functional devices.
