摘要
热固性材料因性能卓越而广泛应用,但难重塑导致资源浪费和环境污染.将动态共价键引入聚合物的交联网络中,可制备兼具热固性材料性能并可重复回收利用的类玻璃高分子材料.文章总结了不同共价键交换类型类玻璃高分子的合成特点,着重阐述了酯交换、二硫交换、亚胺交换的反应机理及优缺点.针对类玻璃高分子的研究现状,分析了其在自修复、可焊接等领域的应用前景,最后结合目前市场需求及材料性能对未来类玻璃高分子的发展前景作出展望.
Abstract
Thermosetting materials are widely used due to their excellent performance,but their difficulty in reshaping leads to resource waste and environmental pollution.By introducing the dynamic covalent bond into the cross-linking network of polymers,vitrimers with thermosetting properties and recyclable properties are prepared.In the article,the synthesis characteristics of different covalent bond exchange types of vitrimers are summarized,and the reaction mechanism,advantages and disadvantages of transesterification,disulfide exchange and imine exchange are emphasized.According to the research status of vitrimers,the application prospects in the fields of self-healing and weldability are analyzed.Finally,according to the current market demand and material properties,the future development prospects of vitrimers are prospected.
