초록
Heat sinks are most widely used in thermal management systems; however, the heat dissipation efficiencyis usually limited. Therefore, in order to increase heat dissipation efficiency of the heat sink, the heat-dissipatingpaint using 2D materials (hexagonal boron nitride (h-BN) and graphene) as thermally conductive additivewas designed and evaluated in the present study. The heat dissipation performance of the paint was calculatedfrom temperature difference between the paint-coated and -uncoated specimens mounted on the heat source. The highest heat dissipation performance was obtained when the ratio of h-BN to resin was 1/10 in thepaint. In addition, further reduction in the temperature of the test specimen by 6.5 oC was achieved. Thehighest heat dissipation performance of the paint prepared using graphene was achieved at a 1/50 ratioof graphene to the resin, and a 6.5 oC reduction was attained. In addition, graphene exhibited enhancedcorrosion resistance property of heat-dissipating paint by inhibiting the growth of the paint blisters.
Abstract

The heat dissipation performance of the paint was calculatedfrom temperature difference between the paint-coated and -uncoated specimens mounted on the heat source.

In addition, further reduction in the temperature of the test specimen by 6.5 oC was achieved.
