摘要
随着材料科学与工程技术的飞速发展,具有优异性能的环氧树脂已成为当前研究的热点,但无法回收重复利用的特性使其难以达到可持续发展的要求。目前,基于动态键的环氧树脂凭借其独特的可调控性、环境响应性及自修复能力,在航空航天、电子信息以及生物医疗等诸多领域展现出极为巨大的应用潜力。本文综述了近年来有关动态键环氧树脂的研究进展,首先阐述了动态键(包括动态共价键与动态非共价键)在环氧树脂体系中的作用机理与分类;随后分别从动态共价键型、动态非共价键型以及动态共价键/非共价键协同作用三方面详细调研了该领域的最新研究成果;最后基于当前研究遭遇的挑战与存在的不足,给出了相应的改进策略以及未来的研究方向。
With the rapid development of materials science and engineering technology,epoxy resins with excellent properties have become a hot research field at present.However,due to their inability to be recycled and reused,they are difficult to meet the requirements of sustainable development.On this basis,dynamic bond epoxy resin materials,with their unique controllable performance,environmental responsiveness and self-repairing ability,have shown great potential for application in many fields such as aerospace,information electronics and bio medicine.This paper reviews the research progress of dynamic bond epoxy resin materials in recent years.Firstly,it elaborates on the mechanism and classification of dynamic bonds(including dynamic covalent bonds and dynamic non-covalent bonds)in epoxy resin systems.Subsequently,it conducts a detailed investigation of the latest research achievements in this field from three dimensions:dynamic covalent bond type,dynamic non-covalent bond typeand the synergistic effect type.Finally,in view of the challenges and deficiencies encountered in current research,corresponding improvement strategies and future research directions are provided.
