| 中文摘要: |
| 烯烃橡胶的强韧化通常通过引入纳米补强剂实现，但补强剂增强的方法存在一些限制。牺牲键是自然材料具有高强韧性的原因之一。利用牺牲键独特的耗能机制，将牺牲键策略引入到烯烃橡胶网络中为其强韧化和功能扩展提供了新思路。介绍了含牺牲键橡胶通过牺牲键断裂和释放隐藏键长耗散能量的耗能机制，综述了通过直接或者简单化学改性的策略将牺牲键引入到橡胶中从而实现对橡胶的增强增韧效应，展望了含牺牲键橡胶的设计与合成、牺牲键在橡胶中的协同效应以及含牺牲键橡胶的功能化应用的发展方向。 |
| 英文摘要: |
| 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. |
