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....
This study focused on the heat transfer enhancement mechanism of micro oscillating heat pipes (MOHP) using self-rewetting fluids (SRWF). SRWFs are believed to improve the thermal performance of heat transfer devices. Thermal conductivity measurements were taken with a thermal analyzer, using the transient plane source method at room temperature. Results found the thermal conductivity of SRWF to be slightly lower than that of water, and MOHP using SRWF exhibited much ...
One way to improve thermal and electrical conductivity of conventional polymers is by combining polymer matrices with highly conductive fillers. This study involves an analysis of electrical and thermal conductivities of nonirradiated and irradiated samples of ethylene vinyl acetate 18 (EVA18) containing expanded graphite (EG) or SDS-EG. Thermal conductivity measurements were at room temperature. An increase in thermal conductivity was found with increasing filler content in all investigated samples, due to ...
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%....
