Vitrimer materials have the capability to trigger covalent bond exchange reactions under both light and heat conditions.This is achieved by introducing covalent bond adaptive networks(CANs)which bring about molecular chain breakage and recombination.As a result,this brings about a change in the topological structure of thermosetting cross-linking networks,thus granting thermosetting materials with superior processability.This breakthrough provides a novel research approach for recycling and reusing thermosetting polymers.Around the research process of vitrimer materials in recent years.It summarizes and comments objectively on the research background and characteristics of vitrimer materials.It also elaborates on the mechanism and performance of vitrimer materials based on ester exchange,imine exchange,disulfide bond exchange,and multiple dynamic bonds.Additionally,it lists the advances in research on vitrimer in recyclable fireproof materials,adhesives,and 3D printing.The paper explores the application scenarios of vitrimer in the industry and analyses the potential development prospects of vitrimer materials.
