In this work, we present a new strategy to engineer novel self-healing ionomers, namely, zwitterionic polymers, and a comprehensive analysis of their mechanical, viscoelastic, and scratch-healing properties. This new method enables reproducible damage of the polymer surfaces, calculation of the scratch volume through tactile profile scans, and quantification of the self-healing efficiency. Based on the results of the scratch tests and complementary rheology, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and hardness tests, new trends, and structure–property relationships can be identified.

新型两性离子聚合物的划痕修复效率的量化

在这项工作中，我们提出了一种工程化新型自修复离聚物（即两性离子聚合物）的新策略，并对其机械，粘弹性和划痕修复性能进行了全面分析。这种新方法能够对聚合物表面进行可再现的破坏，通过触觉轮廓扫描计算划痕量，并量化自愈效率。根据划痕测试和互补流变学，差示扫描量热法（DSC），热重分析（TGA）和硬度测试的结果，可以确定新的趋势以及结构与特性的关系。
