Abstract: During a melt blending process, carbon nanotubes (CNTs) were added to a poly(vinylidene fluoride)/Boron nitride (PVDF/BN) composite, to increase the thermal conductivity of this polymer composite, for uses in the electronic industry. After this process, the thermal and electrical conductivities, along with any microstructure changes were investigated. It was determined that with the addition of CNTs, the thermal conductivity rating of the composite increased, as well as its crystallinity. Also, as CNTs are added to the composite, BN is dispersed homogeneously within the composite and it does not hinder the adhesion of BN/PVDF. It was also noted that the lower the BN content, the higher the dielectric constant, and therefore a lower amount of dielectric loss occurs. Based on the results received, the PVDF/BN/CNT composite may potentially be used in the electronic industry as a heat conductor
