通过静电相互作用实现高性能双网络离子凝胶
作者：
生产高导电性和机械强度高的离子凝胶是开发各种柔性电气设备的迫切需要，但它仍然具有挑战性。在这里，我们报告了一种简单的策略，通过机械坚固的带电凝胶双网络和导电离子液体之间的静电相互作用来制备高性能离子凝胶（离子电导率为1.9 S m−1，断裂应变为170%）。基于带电聚合物网络（有静电相互作用）的离子凝胶比基于中性聚合物网络（无静电相互作用）的离子凝胶具有更高的透光率、离子电导率和更好的力学性能。离子凝胶的双网状结构还可以调节离子凝胶的电导率和力学性能。我们进一步开发了一种使用高性能离子凝胶作为离子导体的离子皮肤传感器，即使在恶劣的条件下也能表现出优异的传感性能。我们设想，这种新型高性能离子凝胶将成为传统水凝胶的一个有吸引力的替代品，并将离子导体的应用扩展到极端环境。
Production of highly conductive and mechanically robust ionogels is urgently needed for the development of diverse flexible electrical devices, but it remains challenging. Herein, we report a facile strategy to prepare high-performance ionogels (ionic conductivity of 1.9 S m−1, fracture strain of 170%) via electrostatic interaction between mechanically robust charged gel double networks and conductive ionic liquids. Ionogels based on charged polymer networks (with electrostatic interaction) exhibit obvious higher optical transmittance, ionic conductivity, and better mechanical properties compared with those based on neutral polymer networks (without electrostatic interaction). Ionic conductivity and mechanical properties of the ionogels can also be regulated by the double-network structure of the gels. We further develop an ionic skin sensor with the high-performance ionogels used as ionic conductors, which can exhibit excellent sensing performance even under harsh conditions. We envision that this new class of high-performance ionogels would be an attractive alternative to traditional hydrogels, and would extend the applications of ionic conductors to extreme environments.
