High thermal conductivity with electrical insulating composite material using BN-MWCNT/PPS core-shell structure via particle coating method |
초록 |
Here we report a highly thermally conductive PPS composite containing boron nitride (BN) and multiwalled carbon nanotubes (MWCNTs) as a thermally conductive filler. The composite was prepared by the particle coating method into polymer pellets in order to obtain high thermal conductivity with low filler concentration, and thus overcome the drawbacks of melt mixing. A comparison between conventional melt mixing and the proposed method showed that the continuous connection of particles at the surface of each pellet led to great enhancement of thermal conductivity. Moreover, the electrically insulating BN layer effectively interrupted electron conduction, which is the major problem with using MWCNTs as a thermally conductive filler, despite their superior thermal conductivity. Our results show that the particle coating method may be used as a promising composite fabrication method for engineering plastics-based thermally conductive materials. |
