Abstract :
We determined the thermal properties of thermal interface materials (TIMs) based on carbon nanotubes (CNTs) and commercial TIMs. The thermal conductivity of different fillers such as CNTs, graphite, nano-diamond, metal, and metal oxide particles (copper and zinc oxide) at different concentrations were studied with a transient plane source technique. For measuring the thermal diffusivity with the Xenon flash method we constructed two novel sample holders and applied them for the measurement of pastes. An open CPU-heat sink setup was used to test interface materials under realistic conditions. Interesting results regarding to the paste composition according to filling content, particle size and viscosity could be obtained.
