The four kinds of boron-containing coupling agents were synthesized, which were applied to improve the interfacial bonding of fluoropolymer/1,3,5-triamino-2,4,6-trinitrobenze (TATB) composite. The boron atom of the coupling agent molecule can form coordinate bond with the fluorine atom of fluoropolymer; and hydrogen atom in its amino group can form hydrogen bond with oxygen atom in nitro-group of TATB. The interfacial performance of the composite was investigated by the measurement of contact angle, surface and interface tension, and adhesive work, and the interfacial bonding mechanism was studied by FTIR and XPS analysis.
