Surface modified boron nitride by epoxy wetting method for fabrication of thermal conductive material |
| 초록 |
Boron nitride (BN) particles fabricated with different surface treatments were used to prepare thermal conductive material by epoxy wetting. The polar functionality present on the BN particles allowed the permeation of the epoxy resin owing to a secondary interaction, which allowed the fabrication of a composite containing high filler concentration. The different cohesive energy densities of the synthesized composite due to a functional-group-induced surface treatment effect on surface free energy and wettability determined the thermal and mechanical properties of the polymer composite. The results indicate that surface-curing agents disturb the interaction between the filler and matrix, and do not always enhance thermal conductivity. Moreover, the composites showed maximum thermal conductivity at 30 wt% epoxy loading when the fixed-pore volume fraction reached in the filtrated BN film. |
