In this study, through the design of the heat transfer path, a high effective heat dissipation material that can easily form a heat transfer path even at a low ceramic filler content is fabricated. When melt-blending with polypropylene(PP), polymethyl methacrylate(PMMA), and polyvinylidene fluoride(PVDF), the PMMA phase can form a continuous phase even at a low volume fraction due to the complete wetting behavior. Using this, we tried to form a continuous heat transfer path efficiently by making the fillers to be localized in the PMMA phase. Boron nitride(BN) filler with the highest affinity for PMMA among three polymers was used, and PMMA with a low molecular weight was used to make it easy to localize the fillers in PMMA phase thermodynamically and kinetically. As a result, the fillers easily formed a heat transfer path along the PMMA phase, allowing for a more efficiently continuous 3D heat transfer path even at a low ceramic filler content.
