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‐repairing binder based on the disulfide bond, the polyurethane binder and FTPB‐PDMI binder based on the Diels‐Alder reaction, and the polyurethane binder based on dynamic photocrosslinking reaction. In addition, PVDF‐co‐HFP/EMIOTf/graphene achieves the self‐repairing behavior of the polymer bonded explosive (PBX). The future development of self‐repairing energetic composites is proposed. It is pointed out that the mechanical properties, processing properties and energy properties should be improved together with the introduction of self‐repairing properties, and the energetic composites which can be repaired in various ways should be prepared.
