Abstract

See full text

A silicone rubber composite heat dissipation pad and a preparation method thereof are provided. The method includes: dispersing hydroxyl-functionalized boron nitride nanosheet powder into deionized water, pouring it into a specialized container, pre-freezing it using liquid nitrogen, and then freeze-drying it to obtain a boron nitride nanosheet skeleton arranged in a horizontal direction; uniformly dispersing thermochromic nanoparticles in acetone to obtain a dispersion, mixing the dispersion with liquid silicone rubber and stirring until acetone is completely evaporated, then adding a curing agent to obtain a liquid silicone rubber pre-cure solution; pouring the liquid silicone rubber pre-cure solution into a container containing the boron nitride nanosheet skeleton, so that the liquid silicone rubber pre-cure solution is fully immersed in an interior of the boron nitride nanosheet skeleton; and then curing is carried out by elevating the temperature to obtain the heat dissipation pad.
