Abstract
A coating composition comprises: exfoliated boron nitride nano sheets (BNNS); and a thermoplastic polymer matrix, wherein the coating composition: (i) has a thermal conductivity greater than or equal to 1.0 W/mK; (ii) has an electric breakdown voltage higher than or equal to 20 kV/mm; and (iii) is pliable. The coating composition can also include the exfoliated BNNS bound to the surfaces of a plurality of co-particles that aligns a plane of the BNNS not parallel to a longitudinal axis of an electromagnetic wire. The non-parallel alignment increases thermal conductivity through the coating. The polymer matrix can be a polyester imide, a polyamide-imide, polysulfones, a polyimide, a polyether ketone, or combinations thereof. Methods of forming the coating include forming the exfoliated BNNS; combining a first monomer and a second monomer to form the thermoplastic polymer matrix; and causing or allowing the exfoliated BNNS to be dispersed throughout the thermoplastic polymer matrix.
