High Thermally Conductive Polymeric Composites

There has been much interest in developing polymeric nanocomposites with ultra-high thermal conductivities such as with exfoliated graphite or carbon nanotubes. These materials exhibit thermal conductivity of 3,000 W/mK measured experimentally and up to 6,600 W/mK predicted from theoretical calculations. But when added to polymers, the expected thermal conductivity enhancement is not realized due to poor interfacial thermal transfer.
