要約(英語): The thermal conductive plate in a device like power module for an automobile requires materials with higher thermal conductivity and acceptable electric breakdown strength. To develop a composite material with both a higher thermal conductivity and acceptable breakdown strength, polymethylmethacrylate (PMMA)/hexagonal boron nitride (h-BN) composite materials in which the flaky surface of h-BN oriented parallel to the electric field and the thermal conductivity measurement (= the sample thickness) direction were produced by an electrostatic adsorption method. The breakdown strength of the PMMA/h-BN composite material showed the increasing trend with the increase of the PMMA particle size. On the other hand, the thermal conductivity of the PMMA/h-BN composite material also showed the decreasing trend with the increase of the PMMA particle size. The h-BN content and/or the orientation rate of the flaky surface of h-BN to the electric field (= the thermal conductivity measurement) direction determine these properties.
