An organic phase change material (PCM), tetradecanol (TD), infused with copper nanowires (CuNWs), was sent through a slurry of tests, to determine the effect of the ultra-high aspect ratio and sponge nature of the CuNWs, on the PCM. Experimental testing alluded to the increased thermal conductivity of the PCM, with the addition of the CuNWs. The addition of CuNWs, enhanced the thermal conductivity of the PCM by nearly 9 times. A ...

This work introduces a direct method for measuring the specific heat of solids, using the Transient Plane Source Technique (TPS). To begin, a sample is placed into a thermally conductive holder, surrounded by a thermally insulating material. A thermally conductive sample holder is used, to limit the time it takes to achieve a temperature equilibrium between the holder and the sensor. Insulating the sample holder is to minimize heat loss ...

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 ...

A novel technique was used in this research article, to introduce a hybrid mesh to a polymer composite within bipolar plates, for proton exchange membrane fuel cells (PEMFCs). The mesh added was copper or aluminum based, to allow for an increased thermal conductivity of the PEMFCs. Experimental testing confirms this theory, as the copper-meshed hybrid polymer composite showed a thermal conductivity of 30.0 W/mK, while the aluminum-meshed hybrid polymer composite ...

In this research article, the thermal conductivity of a polyoxymethylene (POM)/graphite composite was explored. This composite was prepared through an intense process of four intercalation methods; melt, solution, pan milling and in situ intercalation. Graphite is a thermally conductive material, and therefore, it was no surprise when researchers determined that the thermal conductivity of the POM composite increased with the addition of graphite. Thermal conductivity was also noted to ...
