Abstract
To analyze the structure and reinforcing mechanism of boundary layer between nanodiamond and resin matrix, composite resins contained DND (detonation nanodiamond, modified) were synthesized. Properties of resins were investigated by measures of electronic universal testing machine, SEM and FT-IR. The structure and characters of the boundary layer were analyzed and its reinforcing mechanism was explained. Results show that, with the added DND, the mechanical properties of resins is improved, and the boundary layer between DND particle and matrix could be observed. After light-curing, the double bonds in boundary layer were catalyzed and then combined randomly with double bonds of other molecules nearby. Combination between DND and resin matrix changed from week combination, such as hydrogen bonds or intermolecular force, to firm chemical bonds. These changes made resin resistance to load improve greatly.
