Abstract

In this paper, magnetically responsive graphene/boron nitride/iron oxide fillers were prepared by growing iron oxide on the surface of graphene/boron nitride fillers via liquid-phase reaction. By adding the composite filler into the epoxy resin and utilising magnetic field-assisted curing, the composites were prepared to effectively improve the thermal conductivity of the composites while maintaining the insulating properties. The thermal conductivity of the composite filler is 2.1 WmK, and the volume resistance is 4.63 × 10 Ω·cm when the mass ratio of the composite filler is 25%, and the thermal stability and ablation resistance of the composites are improved compared with that of the pure epoxy resin.

摘要

在本文中，通过液相反应在石墨烯/氮化硼填料表面生长氧化铁，制备了磁响应性石墨烯/氮化硼/氧化铁填料。通过将复合填料添加到环氧树脂中并利用磁场辅助固化，制备了复合材料，以在保持绝缘性能的同时有效提高复合材料的热导率。当复合填料的质量比为25%时，复合填料的热导率为2.1W/(m·K)，体积电阻为4.63×10Ω·cm，与纯环氧树脂相比，复合材料的热稳定性和耐烧蚀性得到了提高。
