Abstract

Multiple stretchable gels with conductivity have been thoroughly prepared in diverse solvents historically to modulate their superlative properties in a multitude of applications, such as soft robotics, wearable devices, and e-skins. Eutectogels are considered as an emerging class of gels that combine the best features of both hydrogels and organogels, including environmental friendliness, thermal stability and customizable nature. Eutectogels, composed of deep eutectic solvents (DES) immobilized within different matrices, not only inherit the merits of DES, but also show some additional properties derived from the special structure and compositions, which are conducive to development potential. This review emphasizes the developments and advances in eutectogels from the compositions, functions and applications. Correspondingly, the optimization strategies, mechanisms and advanced progress through solvent engineering and structure tailoring are summarized for multifunctional eutectogels. Then environmental adaptability and intelligent applications in flexible electronics, energy, biology and other fields are discussed in the tailor-made eutectogels. From these recent research efforts of eutectogels and our academic background, the existing challenges and opportunities for future research directions in this filed are thoroughly deliberated at last.

共凝胶的制备、性能和应用

具有导电性的多种可拉伸凝胶已经在不同的溶剂中进行了充分的制备，以调节其在软机器人、可穿戴设备和电子皮肤等众多应用中的最高性能。共凝胶被认为是一种新兴的凝胶，它结合了水凝胶和有机凝胶的最佳特性，包括环境友好性、热稳定性和可定制性。由固定在不同基质内的深层共晶溶剂（DES）组成的共晶凝胶不仅继承了DES的优点，而且由于其特殊的结构和组成而表现出一些额外的性能，有利于发展潜力。本文从共凝胶的组成、功能和应用等方面综述了共凝胶的研究进展。总结了多功能共凝胶的溶剂工程和结构裁剪优化策略、机理和最新进展。然后讨论了定制共凝胶的环境适应性和在柔性电子、能源、生物等领域的智能应用。最后，从这些近年来共析凝胶的研究成果和我们的学术背景出发，对该领域存在的挑战和未来研究方向的机遇进行了深入探讨。
