Abstract: The effects of using different fillers and the effects of filler content and particle size on the thermal properties of thermal interface materials were investigated. The most prominent enhancement in thermal conductivity was observed for samples containing carbon nanotubes and graphite. The filler particle size was also found to significantly affect the thermal conductivity, as smaller fillers resulted in a higher thermal conductivity. The article also describes two sample holders that were tested for the measurement of thermal diffusivity using the laser flash method. The thermal pastes that were prepared were also tested in an open CPU structure to determine how they would react under realistic conditions of use.
