The progress on the methods of improving the interfacial bonding for TATB-based polymer bonded explosive(PBX) in recent years was reviewed. The selection principle for an appropriate binder and how to effectively evaluate the interfacial bonding from the point of TATB molecular structure, as well as the molecular simulation of the interface interaction between TATB and fluoropolymer were summarized. Meanwhile the effect of the surface modification of TATB and coupling agents on the interfacial bonding were mainly described. At last, three key research directions are stated: the structural design of binder, the addition of coupling agents and the new coating method.
