Crosslinked high-performance polymers have many industrial applications but are difficult to recycle. Visual detection of the physical properties of the crosslinked high-performance polymers is useful, but is difficult to achieve. The crosslinked high-performance polymers (SPIN) are constructed by using cation-π interactions. The cation-π interaction between the polymer side chains can be easily installed and removed by aqueous treatments at high or low pH, respectively, which endow the crosslinked polymer with a recyclable behavior. Additionally, the tensile strength and glass transition temperature of the SPIN films could be visually detected by taking advantage of the transparency decreasing effect of cation to an adjacent indole unit.
交联高性能聚合物具有许多工业应用，但难以回收。对交联高性能聚合物的物理性质进行可视化检测是有用的，但很难实现。交联高性能聚合物（SPIN）是通过使用阳离子-π 相互作用构建的。聚合物侧链之间的阳离子-π 相互作用可以通过在高或低 pH 值的水性处理中分别容易地安装和去除，这使交联聚合物具有可回收的行为。此外，通过利用阳离子对相邻吲哚单元的透明度降低效应，可以对 SPIN 薄膜的拉伸强度和玻璃化转变温度进行可视化检测。
