Carbon-Based Passive Thermal Management Material

Applied Nanotech’s new passive thermal management material, CarbAl™, is a carbon-based material with a unique combination of low density, high thermal diffusivity, and low coefficient of thermal expansion.

CarbAl™ has a density of 1.75 g/cm3 compared to 2.7 g/cm3 for aluminum and 8.9 g/cm3 for copper. While copper has a slightly higher thermal conductivity than CarbAl™, 390 W/mK compared to 350 W/mK, CarbAl’s thermal diffusivity is approximately 2.9 cm2/sec compared to 0.84 cm2/sec for aluminum and 1.12 cm2/sec for copper.
