The use of graphene aerogel has recently been studied with highly functional phase change materials (PCMs) to create 3D structures for improved thermal conductivity and shape-stabilization. In this study, hybrid graphene aerogels (HGA) comprising graphene oxide (GO) and graphene nanoplatelets (GNP) were prepared. Thermal conductivity was measured and results found thermal conductivity increased linearly with low GNP content and continued to grow at a slower rate with increased GNP. Improvement ...
This study analyzed the influence of expanded graphite (EG) and sodium dodecylbenzene sulfonate (SDBS) treated EG on the structure and thermal properties of polypropylene. Large surface areas of graphite were found to significantly enhance thermal conductivity and mechanical properties. Thermal conductivity was tested using a thermal constants analyzer. The PP/MAPP/SDBS/EG composites showed better thermal conductivity compared to PP/EG composites....
It has been found that ZnO nanoparticles modify the curing behavior and crossed-line density, among other properties, in epoxy systems. This study aimed at studying the thermo-mechanical properties of ZnO nanoparticles. Thermal properties were measured using a transient plane source technique (TPS) in a thermal constants analyzer. The addition of ZnO nanoparticles caused a decrease of the thermally resistant joints. Despite high thermal conductivity of ZnO-NPs, there was high thermal ...
It was found that the thermal conductivity of composite materials is enhanced by the simultaneous incorporation of dispersed pitch-based carbon fibers (PCFs) and graphene nanoplatelets (GNPs). This study investigated methods for optimizing thermal conductivity. A thermal conductivity analyzer was used to compare thermal conductivity of composites filled with PCF and/or GNP. Results show the values of thermal conductivity increased as the filler content increased, and a greater synergistic improvement ...
In this study, high performance composite phase change materials (PCMs) were created. Graphene oxide (GO) nanosheets were used as supporting materials to keep the shape of polyethylene glycol (PEG) stable during phase change, and graphene nanoplatelets (GNP) were used as conductive fillers. Thermal conductivity was measured with a transient plane source method. Thermal conductivity was found to increase linearly with GNP loading, and PEG/GO/GNP composite PCMs exhibited higher ...
