基于动态共价键的可逆交联聚合物研究进展

Progress in Reversible Crosslinked Polymers based on Dynamic Covalent Bonds

传统高分子材料在研究过程致力于高强、高模量等性能,但在使用过程中不可避免的容易受到损坏甚至报废,材料不可逆的损伤导致资源浪费,污染环境。随着动态共价键概念的提出,自修复材料的开发不仅可以改善生态环境现状,也可以延长材料的使用寿命,对经济的可持续发展也有着重要的推动作用。文章根据动态共价键的反应机理,概述了将动态共价键的类型以及将其引入高分子聚合物的研究现状及优势,并对自修复聚合物的应用进行了概括。

Traditional polymer materials are committed to high strength, high modulus and other properties in the research process,but in the use process is inevitably prone to damage or even scrap, irreversible damage of materials lead to resource waste and environmental pollution. With the proposed concept of dynamic covalent bond, the development of self-healing materials can not only solve the deterioration of ecological environment, but also extend the service life of materials, which plays an important role in promoting the sustainable development of economy. Based on the reaction mechanism of dynamic covalent bonds, this paper summarizes the types of dynamic covalent bonds and the research status and advantages of introducing them into polymers, and summarizes the application of self-healing polymers.
