Electrically conductive hydrogels for flexible energy storage systems
近年来，可穿戴设备、软体机器人以及可折叠显示等柔性电子产品受到了广泛的关注，开发与之匹配的柔性储能器件成为当前学术界和产业界的研究热点。导电水凝胶结合了导电高分子的电化学性能与水凝胶的柔软特性，具有大比表面积，出色的电子传输与离子传输能力，是构筑柔性电极的理想材料。
In recent years, flexible electronics such as wearable devices, soft-bodied robots and foldable displays have received extensive attention, and the development of flexible energy storage devices has become an extensive research interest in the academic and industrial fields.Electrically conductive hydrogels (ECHs) are an emerging class of hydrogels combining a hydrophilic matrix with electrically conductive fillers, such as metallic nanoparticles, conductive polymers(CPs), or carbon-based materials. ECHs have exceptional promise in many applications ranging from renewable energy, flexible electron, and environmental engineering to medical devices and drug delivery systems.

本综述首先论述了纳米结构导电水凝胶的合成与功能化策略及其独特的物理与化学特性。根据高分子水凝胶网络以及导电填充物的种类，导电水凝胶的合成方法主要包括交联聚合物链或单体以构建三维纳米结构的聚合物链网络。其次介绍了导电水凝胶材料中的渗流理论。最后从导电凝胶材料结构化和功能化的角度系统地梳理了纳米结构功能化水凝胶在能量存储方面（锂离子电池和超级电容器）的最新研究进展，并指出了该领域的挑战和机遇。
In this review, the synthesis and functionalization strategies of nanostructured ECHs and their unique physical and chemical properties are first described.According to the polymer hydrogel network and the type of conductive filler, the synthesis methods of ECHs mainly include crosslinking polymer chains or monomers to build a three-dimensional nano-structure polymer chain network. Then,the percolation theory of ECHs is introduced. At last, the latest research progress in energy storage (Li-ion batteries and supercapacitors) of nanostructured functional hydrogels is systematically reviewed from the perspective of structure and functionalization of ECHs, and the challenges and opportunities in this field are pointed out.
