摘要
Abstract Self‐healing polymer materials have been developed rapidly over the past 20 years, which can replace thermosetting materials to a certain extent, repair damage without manual intervention, prolong service life, and compress usage cost. The self‐healing polymer materials derived from biomass resources can reduce the dependence on traditional non‐renewable resources such as petroleum. The structures and properties of biomass based self‐healing polymer materials are of great significance for their processing, recycling and self‐healing. In this paper, the research progress of bio‐based self‐healing polymer materials based on dynamic non‐covalent bonds and dynamic covalent bonds including hydroxyl ester, Schiff base, disulfide bond, and hydroxyl urethane derived from vegetable oil, lignin, cellulose, vanillin and natural rubber were reviewed, and the dynamic non‐covalent bonds and dynamic covalent bonds were also introduced. The applications of various dynamic covalent bonds and dynamic non‐covalent bonds in the design and construction of polymer materials were reviewed, and the future development of dynamic covalent polymer materials was prospected.
