自愈合离子凝胶的制备及传感测试

School of Chemical Science and Engineering, Tongji University, Shanghai 200092, China

Received Date: 1 March 2022

制备可自愈合离子凝胶及测试其应变和湿度感应，可用作本科新生的普通化学实验，经拓展内容后也适用于应用化学、高分子化学和材料科学与工程等相关专业本科生的综合实验。实验采用自由基聚合法将1-乙烯基-3-丁基咪唑四氟硼酸盐（[VBIm][BF₄]）制备成交联聚合物凝胶（PIL），1-丁基-3-甲基咪唑四氟硼酸盐（[BMIm][BF₄]，IL）充盈其中作为溶剂和添加剂。该PIL/IL离子凝胶中存在游离态的离子液体，具有良好的导电性，可对应变和湿度变化产生响应；同时，因具有较强离子键相互作用，该离子凝胶具有自愈合能力，可重复使用。
