In this study, various filler loadings of thin graphite sheets were added to epoxy adhesives to improve thermal conductivity. Natural graphite powder and graphite nanoflakes were used as reference fillers in the same resin, and the thermal conductivity of each filler was measured with a TPS thermal constants analyzer based on the transient plane source (TPS) method. Results showed that the graphene sheets enhanced the thermal conductivity by more than 22 ...
Asphalt solar collector (ASC) is a conductive asphalt concrete and an eco-friendly method to de-ice roadways. This study examined if the addition of conductive fillers and various mixing parameters could improve the thermal conductivity and energy efficiency of ASC. A thermal conductivity system measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that thermal conductivity was mostly improved by higher asphalt temperatures, ...
Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared using thermally conductive exfoliated graphite (EG) fillers and pMDI additives. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the EG-carbon foams and the EG/pDMI-carbon foams showed significantly ...
Nitrate materials play an important role in the development of latent thermal energy storage (LTES) systems. This paper examined the thermo-physical properties of sodium nitrate, potassium nitrate and their mixtures with expanded graphite (EG) additives for their applications in solar energy storage. The transient hot-wire method measured the apparent thermal conductivities of the nitrates and nitrates/EG mixtures. Results showed that nitrates/EG mixture PCMs with the highest concentrations of ...
Aspects of hydrogen distribution systems need improvement for their applications in fuel cell vehicles. In this paper, chemical and physical characteristics of the H2 storage material, sodium aluminum hydride (SAH), were examined after the samples were compacted and Expanded Natural Graphite (ENG) worms were added. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the SAH pellets with (ENG) worms using the Transient Plane Source (TPS) method. Results showed ...
