Research Progress of Effect of Dynamic Reversible Network on Performance of Rubber Composites

论述动态可逆网络构建对橡胶材料性能影响的研究进展。动态可逆网络的构建主要基于非共价键和动态可逆共价键,非共价键包括氢键和离子键,生成动态可逆共价键的主要方法有Diels-Alder反应、β-羟基酯交换反应和双硫交换等。目前动态可逆网络在橡胶材料中的应用还存在一些问题,如采用氢键和离子键构建动态可逆网络导致橡胶材料性能不稳定、动态可逆网络构建工艺复杂等。在不牺牲橡胶材料原有应用性能的基础上,通过匹配橡胶材料工业成型工艺来构建稳定的动态可逆网络以赋予橡胶材料可重复加工性和自愈性,是未来研究的主要方向。

The research progress of the effect of dynamic reversible network on the performance of rubber composites was discussed.The construction of dynamic reversible network was mainly based on noncovalent bond which included hydrogen bond and ionic bond and dynamic reversible covalent bond.The main methods to generate dynamic reversible covalent bond included Diels-Alder reaction,β-hydroxyl ester exchange reaction and disulfide exchange.At present,there were still some problems in the application of dynamic reversible network in rubber composites,such as the unstable properties of rubber composite with the network formed by hydrogen and ionic bonds,and the complexity of the network construction process.Therefore,the main direction of future research was to construct a stable dynamic reversible network which could be incorporated into the current industrial manufacturing process without sacrificing any application performance,and the resulted rubber composites possess re-processing and self-healing properties.
