In order to improve the adaptability of bonding agent to various energy-containing fillers and modify the interfacial bonds of solid propellants， a kind of multifunction telechelic bonding agent was designed and prepared. The bonding effectiveness was studied by molecular dynamics simulations and experimental evaluations. The results show that this bonding agent can show decent interactions with various energy-containing fillers. By altering the molecule backbone of this bonding agent， it can adapt to different adhesive systems. As compared to the three-claw bonding agent， the two-claw one has fewer branches， better diffusivity in adhesive， higher transferability toward interface， and better bonding effectiveness.
