Abstract:
      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.
