Synthetic graphite particles were added to a liquid crystal polymer and then these composites were tested for through-plane and in-plane thermal conductivity using the TPS method. The authors expanded on an empirical model created to determine the relationship between thermal conductivity and volume percent of filler. This empirical model can now be used to approximate the in-plane thermal conductivities for a range of applications....
Through the addition of graphite powder (GP) and expanded graphite (EG) the authors were able to increase the thermal conductivity of a shape-stabilized paraffin/high density polyethylene (HDPE) composite phase change material (PCM). GP and EG were added in different mass fractions and a Thermal Constants Analyzer was used in order to measure the thermal conductivity. The relationship between mass fractions of GP and EG added were found to have ...
This research aims to determine the effect of altering filler particle sizes and shapes, on the thermal and mechanical properties of polypropylene (PP). Fillers such as thermally reduced graphite oxide (TRGO), multi-layer graphene (MLG250), carbon black (CB), multiwalled nanotubes (MWNT) and expanded graphite (EG), were added to the PP base. A thermal analyzer was used to measure the thermal conductivity of the various PP composites. Results determined that the PP ...
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 ...
