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 ...
