Epoxy composites with different orientation degree of nano BN were prepared by applying different DC electric fields during the curing process of BN/epoxy resin mixture, and the influences of different electric field strength on the orientation degree of BN nanosheet were studied, while the influences of orientation degree of BN nanosheet on the thermal conductivity and electrical properties of epoxy composites were discussed. The results show that with the increase of DC electric field strength, the orientation of BN nanosheet is closer to electric field direction, the thermal conductivity of epoxy composites is improved, and the dielectric constant and electrical conductivity increase. By adjusting the distribution and orientation of BN nanosheet, the thermal conductivity and insulating properties of epoxy composite are improved synergistically.
