The present study aims at encapsulating hybrid graphene aerogel (HGA) into 3D graphene foam (GF) to fabricate high-performance composite phase change materials (PCM). Using the chemical vapor deposition (CVD) technique, a 3D hybrid GF/HGA (GH) microstructure was formed to create PW/GH composite PCMs. Thermal conductivity of PW/GH composite PCMs increased due to optimized 3D GH hybrid microstructure....
Research found tannins have been successful as monomers to produce organic foams with superior properties for thermal insulation. Norway spruce (Picea abies) tannins were extracted and used to prepare tannin/furanic foams. Thermal conductivity measurements were taken by transient plane source method. Thermal conductivity performance improved with higher closed-cell content in the foam....
In this study, expanded graphite (EG) was crushed and the resulting composites were filled with various amounts of EG using a melt-mix method. Thermal conductivity was then analyzed to investigate the possible synergistic enhancement through self-hybridization. Thermal conductivity was measured at an ambient temperature and normal pressure. Composites filled with 10 wt% EG and wEG fillers improved thermal conductivity, compared to composites containing one type of filler at 20 wt%....
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 ...
