In this study, boron nitride (BN)/polymethyl methacrylate (PMMA) composites are prepared by in-situ polymerization for high thermal conductivity. The surface of BN was silanized with vinyltriethoxysilane to introduce carbon-carbon double bonds, and it was directly linked with the polymer chains during the polymerization step. As a result, at a BN content with 70 wt.%, the composite exhibited an obvious thermal conductivity enhancement, with a value that was 17.8 times higher than that of PMMA. In addition, our composites were also compared to other BN/PMMA composites fabricated with conventional melt-mixing and showed higher thermal conducitivities. |
