Over the past two decades, deep eutectic solvents (DESs) have captured significant attention as an emergent class of solvents that have unique properties and applications in differing fields of chemistry. One area where DES systems find utility is the design of polymeric gels, often referred to as "eutectogels," which can be prepared either using a DES to replace a traditional solvent, or where monomers form part of the DES themselves. Due to the extensive network of intramolecular interactions (e.g., hydrogen bonding) and ionic species that exist in DES systems, polymeric eutectogels often possess appealing material properties-high adhesive strength, tuneable viscosity, rapid polymerization kinetics, good conductivity, as well as high strength and flexibility. In addition, non-covalent crosslinking approaches are possible due to the inherent interactions that exist in these materials. This review considers several key applications of polymeric eutectogels, including organic electronics, wearable sensor technologies, 3D printing resins, adhesives, and a range of various biomedical applications. The design, synthesis, and properties of these eutectogels are discussed, in addition to the advantages of this synthetic approach in comparison to traditional gel design. Perspectives on the future directions of this field are also highlighted.
在过去的二十年中，深共晶溶剂（DESs）作为一类新兴的溶剂引起了人们的极大关注，它们在化学的不同领域具有独特的性质和应用。DES 系统的一个应用领域是设计聚合物凝胶，通常称为“共晶凝胶”，可以使用 DES 代替传统溶剂来制备，或者单体本身就是 DES 的一部分。由于 DES 系统中存在广泛的分子内相互作用（例如氢键）和离子物种，聚合物共晶凝胶通常具有吸引人的材料性质，如高粘合强度、可调粘度、快速聚合动力学、良好的导电性以及高强度和柔韧性。此外，由于这些材料中存在固有相互作用，因此可以采用非共价交联方法。本文综述了聚合物共晶凝胶的几个关键应用，包括有机电子、可穿戴传感器技术、3D 打印树脂、胶粘剂以及各种生物医学应用。讨论了这些共晶凝胶的设计、合成和性质，以及与传统凝胶设计相比，这种合成方法的优势。还强调了该领域未来发展方向的观点。
