本征型自修复橡胶材料的研究进展

Research Progress on Intrinsic Self-healing Rubber

介绍本征型自修复橡胶材料的研究进展。本征型自修复橡胶材料是利用自身的可逆交联化学反应来修复损伤,不添加修复剂就能实现多次修复。基于可逆非共价键的自修复方法包括利用氢键、离子键和配位键形成的交联网络实现橡胶材料的自修复,基于可逆共价键的自修复包括利用Diels-Alder反应和二硫键可逆反应实现橡胶材料的自修复,利用橡胶的环氧化也可实现橡胶材料的自修复。本征型自修复橡胶材料可多次修复和循环利用,不同方法制备的自修复橡胶材料的修复率不同,希望通过适合的工艺制备兼顾良好物理性能和自修复性能的橡胶材料。

The research progress of intrinsic self-healing rubber materials was introduced.The intrinsic self-healing rubber material used its own reversible cross-linking chemical reaction to repair the damage,and could be repaired multiple times without adding a repair agent.Self-healing methods based on reversible non-covalent bonds included the use of cross-linked networks formed by hydrogen bonds,ionic bonds and coordination bonds to achieve self-healing function of the rubber materials.Self-healing methods based on reversible covalent bonds included the use of Diels-Alder reaction and disulfide bond.The use of rubber epoxidation could also realize the self-healing of rubber materials.The intrinsic self-healing rubber materials could be repaired and recycled for many times,and the repair proportion of the self-healing rubber materials prepared by different methods was different,and it was hoped that the rubber materials with good physical properties and self-healing properties could be prepared by suitable technology.
