【摘要】 动态聚合物因结构中含有动态键而会在外界刺激(如光、热及pH等)下做出响应,因此具备一些特殊性能,成为高分子材料领域一个重要的研究方向。动态键包括动态非共价键和动态共价键,文中简要介绍了2类动态键的特点及常见的动态键,进一步回顾和总结了动态聚合物的自修复、高拉伸、可回收、形状记忆等特殊性能,并简要对动态聚合物所面临的挑战和关键问题进行了展望。更多还原

【Abstract】 Dynamic polymers, because of dynamic bonds in their polymer structures, can be responsive to external stimuli(such as light, heat, and pH etc.) and have some special properties, which have become an important research direction in the field of polymeric materials. Dynamic bonds include dynamic non-covalent bonds and dynamic covalent bonds. This paper briefly introduced the characteristics of two types of dynamic bonds and the common dynamic bonds, and further reviewed and summarized the special properties of dynamic polymers, such as self-healing capability, high stretchability, recyclability, shape memory performance, and solid-state plasticity. In addition, the challenges and key problems of dynamic polymers were also expected.更多还原
