Characterization on surface and interfactial properties of nitramine crystal fillers and polymeric bonding agents

摘要

The surface and interfacial properties of polymeric bonding agents and nitramine crystal fillers were studied. The surface free energy and adhesion work of polymeric bonding agents and nitramine fillers were calculated by using Kaeble's equations. It was observed that the hydroxyl values of neutral polymeric bonding agents (NPBA) correlate well with the polar components of surface free energies. On the basis of the measurements of swelling ration and initial modulus, the interfacial bonding through highly corosslinked polymeric shell formation around the nitramine particles and generating interfacial reinforcement were rationalized.
