摘　　要：介绍了类玻璃高分子(vitrimer)材料的发展史、拓扑冻结转变温度,对基于酯交换、烷基转移和转氨基化的vitrimer动态机理和基于木质素、植物油、纤维素和香草醛的生物基vitrimer的研究进行了概述,并对生物基vitrimer材料进行了展望。Vitrimer is a type of polymer that combines the advantages of traditional thermosetting and thermoplastic polymers and is capable of network reorganization under the stimulation of external conditions to maintain good mechanical properties and allow repeatable molding processes.This has generated a great impact to the fields of self-healing of materials and corresponding design of shape-memory smart polymers.This paper introduced the history of vitrimer materials and the topological freezing transition temperature.The paper also gave an overview of the study on the dynamic mechanism of vitrimer based on the ester exchange,alkyl transfer,and transamination.In addition,the bio-based vitrimers based on lignin,vegetable oil,cellulose,and Vanillin were discussed in detail,and an outlook on vitrimer as a class of materials were prospected.
