动态共价聚合物网络早已被认识。随着最初关注动态共价键对商业橡胶粘弹性的意外影响，现代的努力已经过渡到设计具有独特自适应特性的动态共价聚合物网络。自修复和热固性再加工一直是研究动态共价聚合物网络的主要动机，最近发现的这种材料的玻璃化流变行为和固态塑性为材料创新开辟了新的机会。这一点，再加上商业上相关的聚合物结构单元，如酯和酯的动态特性的启示，表明这类材料的一个充满希望的未来。
Dynamic covalent polymer networks have long been recognized. With the initial focus on the unintended impact of dynamic covalent linkages on the viscoelasticity of commercial rubbers, efforts in modern times have transitioned into designing dynamic covalent polymer networks with unique adaptive properties. Whereas self‐healing and thermoset reprocessing have been the primary motivations for studying dynamic covalent polymer networks, the recent discovery of the vitrimeric rheological behavior and solid‐state plasticity for this type of material have opened up new opportunities in material innovations. This, coupled with the revelation of the dynamic characteristics of commercially relevant polymer building blocks such as esters and urethanes, suggests a promising future for this class of materials.
