| Abstract: |
| In recent years，self-healing materials attracted more and more attention. According to the repair mechanism，self-healing materials could be divided into foreign aid type and intrinsic type. Intrinsic self-healing materials had more important practical value and research significance. In this paper，the latest research progress of intrinsic self-healing elastomers based on non-covalent bond system，reversible covalent bond system and multiple dynamic bond composite system in recent years were reviewed，the problems faced by the research of self-healing elastomers were summarized，and the research direction of self-healing elastomers were pointed out. An opinion was put forward that in addition to the research on the synthesis and performance characterization of self-healing elastomers，the physical mechanism of self repairing elastomer damage and repair should also be revealed at the molecular scale. |
