Thermal greases are vital for electronic temperature regulation and overall performance. Improved thermally conductive greases have been made utilizing hyrdogen bonding of carbon nanotubes (CNT) and hexagonal boron nitride (hBN). Nanomaterial fabricated greases have similar material characteristics including viscosity as market thermal greases but have enhanced thermal properties for heat transfer. These greases show improvements of up to 80% in thermal conductivity measurements. CPU testing resulted in 100% decrease in standard deviation of temperature from commercial grease variation.
