The effects of the addition of three different fillers to a polymer matrix on the thermo-physical properties of the resulting composites were investigated by the authors. Boron nitride, synthetic diamond, and silicon nitride were used as the fillers (up to 2 vol. %), and it was found that their addition did increase the thermal conductivity relative to that of the pure epoxy matrix. Furthermore, it was determined that the thermal conductivities of ...
In this paper, polyamide (PA, composed of at least 60% renewable materials) was used as a polymer matrix to prepare PA-hexagonal boron nitride (hBN) polymer composites with varying hBN contents. Two different PA samples were used in this study: a low viscosity grade PA (PA-30), as well as a high viscosity grade PA (PA-90). The composite polymers were tested to evaluate their thermal, physical, and mechanical properties. It was concluded that ...
Polyactic acid (PLA)-micro hexagonal boron nitride (hBN)-graphene nanoplatelet (GNP) polymer composites were prepared, and the effects of varying filler contents on the thermal and mechanical properties of the polymer composites were investigated. It was determined that the addition of the GNPs resulted in a decrease in thermal conductivity in comparison to a PLA-hBN composite unless the GNP:hBN ratio was 1:1, where the thermal conductivity was equal to that ...
A paraffin-based composite phase change material (PCM) was prepared by the addition of hexagonal boron nitride (h-BN) nanosheets to melted paraffin wax followed by vigorous stirring. The nanosheets were added in quantities ranging from 1 to 10 wt. %. A reference sample of pure paraffin was also prepared. It was determined that the addition of h-BN nanosheets resulted in an increase in thermal conductivity and that the melting and solidification rates were also ...
