Abstract Nanosecond pulsed electric fields over 200kV/mm have been used for filler alignment in polymer-based thin film (120~250μm) composites to improve their thermal conductivity, but little research has been performed on bulk composites because of the requirement of an extremely high nanosecond pulsed voltage. In this paper, a microsecond pulsed voltage, whose pulse width was 1μs, and electric field was only 11.76kV/mm, was adopted for the first time to prepare bulk composites of 1.7mm. Effects of frequency on orientation and thermal conductivity of composites were studied. The degree of orientation was determined based on cross-sectional scanning electron microscopy (SEM) and X-ray diffraction (XRD) peaks. The results show that the orientation degree and thermal conductivity increase with the increasing frequency, but the increase rate is lower under higher frequencies. The thermal conductivity under 100 Hz is 0.588W/mK, which is more than twice that of composites without application of electric field (0.286W/mK). Additionally, AC breakdown strength was measured, the results show that after BNNSs orientation, the composites still have better AC breakdown performance than pure epoxy resin.

Key words： Microsecond pulsed electric field orientation epoxy resin BN nanosheets thermal conductivity
