Ionogels have aroused wide interests in the field of flexible electronics. The combination of solid-state networks and ionic liquids opens up thousands of possibilities for ionogels. The unique structures of ionogels endow them excellent mechanical properties, conductivity and thermal stability to approach the challenge of flexible electronic. A large number of new ionogels have been developed by different methods including the exchange of solution, polymeric ionic liquid and in-situ reactions in ionic liquids (gelation of low molecular weight gelators, self-assembly of block polymers, formation of double-network structure, ionogel nanocomposites and direct polymerization of polymerizable monomers). The aim of this review is to discuss different preparation methods of ionogels and the comparison of their advantages.
离子凝胶在柔性电子领域引起了广泛关注。固态网络与离子液体的结合为离子凝胶带来了无数可能性。离子凝胶独特的结构赋予它们优异的机械性能、导电性和热稳定性，以应对柔性电子的挑战。通过不同方法已开发出大量新型离子凝胶，包括溶液交换、聚合离子液体以及离子液体中的原位反应（低分子量凝胶剂的凝胶化、嵌段聚合物的自组装、双网络结构的形成、离子凝胶纳米复合材料以及可聚合单体的直接聚合）。本综述旨在讨论离子凝胶的不同制备方法及其优势比较。
