Dynamic covalent polymeric networks (DCPNs) with hindered urea bonds and free thiol groups were prepared. Due to the catalyst-free conversion of dynamic hindered urea bonds to dynamic thiourethane bonds, these materials showed enhanced mechanical properties along with time or triggered by elevated temperature, and exhibited excellent self-healing performance.
制备了具有受阻脲键和游离巯基的动态共价聚合物网络（DCPNs）。由于动态受阻脲键无催化剂转化为动态硫代氨基甲酸酯键，这些材料表现出增强的机械性能，随时间或升高的温度而增强，并表现出优异的自修复性能。
