Carbon nanotubes have a typical thermal conductivity range of 3000 to 3500 W/m•K [watts per meter per degree Kelvin]. Diamond, another form of carbon, comes in between 1000 and 2200 W/m•K. The single-layer graphene studied by the UCR researchers displayed a thermal conductivity as high as 5300 W/m•K near room temperature. The thermal conductivity of silicon, the most important electronic material, is around 145 W/m•K if measured at room temperature. Graphene is 36.5 times better than silicon at conducting heat.
