摘要
The strengthening and toughening of diene rubbers were usually achieved by introducing nano fillers，whereas this method had some limitations. Sacrificial bond was one of the important reasons why natural materials processed good strength and toughness. The introduction of sacrificial bonds into diene rubber networks was an alternative way to achieve strengthening and toughening of diene rubbers and expand their functional applications by using the unique energy dissipation mechanism of sacrificial bonds. In this review，the energy dissipation mechanism of rubbers containing sacrificial bonds by bond breaking and hidden length releasing to realize the strengthening and toughening effect. The introduction methods of sacrificial bonds into rubbers by direct or simple chemical modification strategy were reviewed. Besides，the development of the design and synthesis of rubbers containing sacrificial bonds，the synergistic effect of sacrificial bonds in rubbers and functional application of rubbers containing sacrificial bonds were discussed. ? 2020 Tunnel Construction.
