要約(英語): An electrostatic adsorption method can produce composite materials with an arbitrary structure. To develop a composite material with a higher thermal conductivity and acceptable breakdown strength, a thermal conductive Polymethylmethacrylate (PMMA) / Boron nitride (BN) composite insulating material is produced using an electrostatic adsorption method. The breakdown strength of the PMMA/BN composite as a function of the PMMA particle size showed a peak. It was recognized from the observation of SEM image that the increase of the distance between fillers which leads to increase of breakdown strength, and the increase of the orientation ratio of longer direction on the BN to electric field direction which leads to decrease of breakdown strength. These balances may determine the breakdown strength. On the other hand, the thermal conductivity exhibited the increasing trend with the increase of the PMMA particle size. The increase of the orientation ratio of longer direction on the BN to the thermal conductivity measurement direction may bring to higher thermal conductivity with the increasing PMMA particle size. It was clarified that the electrostatic adsorption method can easily produce the composite material with different properties for different purposes by changing the PMMA particle size.
