Thermal interface materials with radiative coupling heat transfer

Abstract:

A thermal interface material, a process of forming a thermal interface, the thermal interface including the thermal interface material, and an article of manufacture including the thermal interface material, where the thermal interface material includes polar nanoparticles embedded in one or more carrier materials. The polar nanoparticles may have a diameter of approximately 50-60 nanometers or less, and near-field radiative coupling between the polar nanoparticles. The process of forming the thermal interface including: obtaining the polar nanoparticles; adding the polar nanoparticles to one or more carrier materials to form a carrier mixture, where the polar nanoparticles are embedded in the one or more carrier materials; creating a thermal interface material using the carrier mixture; applying the thermal interface material to a first electronics component and a second electronics component; and compressing the electronics components, where the compressing densely packing the polar nanoparticles.
