Abstract:

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.

Key words: dynamic covalent bond, biopolymer, vitrimer
