本文综述了水凝胶的基本概念--分类、涉及的聚合物、合成方法、水凝胶的类型、性质和应用。水凝胶可由天然聚合物、合成聚合物、可聚合合成单体以及天然聚合物和合成聚合物的组合合成。水凝胶的合成包括物理、化学和杂化成键。键合是通过溶液浇注、溶液混合、本体聚合、自由基机理、辐射方法和互穿网络形成等不同途径形成的。合成的水凝胶具有显著的机械强度、生物相容性、生物降解性、溶胀性和刺激性敏感性。这些性质对于电化学和生物医学应用是非常重要的。此外，该综述还强调了柔性和自愈性水凝胶作为电解液在能量存储和能量转换中的应用。电极和电解液之间的粘附性不足(界面相互作用较少)和机械强度不足带来了严重的挑战，如超级电容器、电池和太阳能电池的分层。由于智能和水性的水凝胶，坚固的机械强度、粘附性、延伸性、应变敏感性和自愈性是衡量储能和转换装置可靠性和稳健性的关键因素。在当前的十年中，这些设备对于智能、轻质、可折叠的电子产品和现代无污染交通来说是高效和方便的。
In the present review, we focused on the fundamental concepts of hydrogels—classification, the polymers involved, synthesis methods, types of hydrogels, properties, and applications of the hydrogel. Hydrogels can be synthesized from natural polymers, synthetic polymers, polymerizable synthetic monomers, and a combination of natural and synthetic polymers. Synthesis of hydrogels involves physical, chemical, and hybrid bonding. The bonding is formed via different routes, such as solution casting, solution mixing, bulk polymerization, free radical mechanism, radiation method, and interpenetrating network formation. The synthesized hydrogels have significant properties, such as mechanical strength, biocompatibility, biodegradability, swellability, and stimuli sensitivity. These properties are substantial for electrochemical and biomedical applications. Furthermore, this review emphasizes flexible and self-healable hydrogels as electrolytes for energy storage and energy conversion applications. Insufficient adhesiveness (less interfacial interaction) between electrodes and electrolytes and mechanical strength pose serious challenges, such as delamination of the supercapacitors, batteries, and solar cells. Owing to smart and aqueous hydrogels, robust mechanical strength, adhesiveness, stretchability, strain sensitivity, and self-healability are the critical factors that can identify the reliability and robustness of the energy storage and conversion devices. These devices are highly efficient and convenient for smart, light-weight, foldable electronics and modern pollution-free transportation in the current decade.
