Abstract: Using a solid hot stretching technique, highly-oriented polyoxymethyelen (POM)/multi-walled carbon nanotubes (MWCNTs) composites were created. Thermal properties were analyzed both in the stretched and through-plane directions. Researchers found that by increasing the draw ratio, to as high as 900%, the thermal conductivity of the composite has improved in the stretching direction, when compared to the material prior to this process. Researchers also determined that the thermal conductivity of the MWCNTs composite can reach as high as 1.2 W/mK, after the stretching process.
