Progress in Preparation and Application of Vitrimers Based on Dynamic Covalent Bonds
摘要
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.关键词
