What Are Some Key Materials with High Thermal Conductivity?
1. Graphene: Known for its extraordinary thermal conductivity, graphene can conduct heat better than any other known material. Its thermal conductivity can exceed 5000 W/m·K. 2. Carbon Nanotubes: These cylindrical nanostructures also exhibit high thermal conductivity, especially in their axial direction. Multi-walled carbon nanotubes have thermal conductivities up to 3000 W/m·K. 3. Boron Nitride Nanotubes: Similar in structure to carbon nanotubes, these materials combine high thermal conductivity with electrical insulation properties. 4. Diamond: Nanodiamonds offer high thermal conductivity and are widely used in heat sinks and thermal interface materials.
