The incorporation of hybrid fillers has been proposed as a strategy to reduce the interfacial thermal resistance between the filler and the matrix and improve the thermal conductivity of the polymer composites. Moreover, boron nitride, which has a one-dimensional (1D) and two-dimensional (2D) structure similar to carbon allotrope has attracted attention as an inorganic filler suitable for composites with high thermal conductivity and low electrical conductivity. In this study, the optimal content of 1D and 2D boron nitride hybrid fillers-based composites to achieve high thermal conductivity was systematically obtained. The epoxy composite with 48.90 vol% of h-BN and 0.63 vol% of BNNT showed the highest thermal conductivity of 10.93 W/m·K, and this result supported the suitability of inorganic hybrid nano-fillers for polymer composites exhibiting high thermal conductivity and low electrical conductivity.
