Bioinspired construction of BN@polydopamine@Al2O3 fillers for preparation of a polyimide dielectric composite with enhanced thermal conductivity and breakdown strength

This paper reports that a novel polyimide dielectric composite with three-dimensional (3D) thermally conductive networks and enhanced breakdown strength was firstly fabricated by filling with core-double-shell structured F-BA fillers. The F-BA particles were composed of nano-sized boron nitride (nBN...
