摘要
This review summarizes research progress in self-repairing energetic composites based on the design of chemical structure of binders and the introduction of self-repairing properties between composite interfaces.Researchers have prepared the polyurethane-urea binder and the GAP self-repairingbinder based on the disulfide bond,the polyurethane binder and FTPB-PDMl binder based on the Diels-Alder reaction,and the polyurethane binderbased on dynamic photocroslinking reaction.In addition,PVDF-coHFP/EMIOTf/graphene achieves the self-repairing behavior of the polymer bondedexplosive(PBX).The future development of elf-repairing energetc composites is proposed.lt is pointed out that the mechanical properties,processingproperties and energy properties should be improved together with the introduction of self-repairing properties,and the energetic composites whichcan be repaired in various ways should be prepared.
