Effect of the Pressure on the Interface and thermal diffusivity of Polypropylene-SiC Composites |
| 초록 |
The effect of pressure on the thermal diffusivity in two-phase composite system was studied. thermally conductive polypropylene (PP)/silicon carbide (SiC) composites were prepared by applying various pressures from 0 to 20 MPa. The thermal diffusivity of the composite was increased at 20 MPa by 40% compared to the value of at 0 MPa. It was 9 times higher than that of unfilled polypropylene. It implies the pressure induces the easy path for phonon transport. Also, the ezperimental values were compared with Maxwell's prediction and Agari's prediction. Agari's prediction gave a better agreement compared to that of Maxwell's prediction due to the consideration of interactions between filler-filler and filler-polymer. |
