Abstract

Thin films of a stimuli-responsive homopolymer dewet as a stimulus response after anion exchange of the imidazolium's counter anion. Contact angle analysis and interfacial energy considerations indicate dewetting goes counter to increasing spreading coefficient. Intrafilm stress arising from structural relaxation drives the dewetting.

摘要

刺激响应均聚物薄膜在进行离子交换后会作为响应刺激而脱湿，其反离子为咪唑鎓。接触角分析和界面能考虑表明脱湿与增加的铺展系数相反。结构弛豫引起的内部分应力驱动脱湿。
