This paper examined the thermophysical properties of hydrate using disodium hydrogenphosphate 12H2O to develop a long-term latent heat storage (LTLHS) using supercooling. The thermal conductivities of solid and liquid disodium hydrogenphosphate 12H2O were measured using the transient plane source (TPS) technique. Results showed that the thermal conductivity of liquid disodium hydrogenphosphate 12H2O increased slightly with temperature, whereas the solid phase showed a minor downward trend. Also, thermal ...
Phase change materials (PCMs) are an attractive solution for reducing energy usage because of their efficient latent heat storage abilities. This paper examined chemical and physical properties of micro-PCMs before and after their integration with concrete samples. A Thermal Constants Analyser (TPS) measured the thermal conductivity of the PCM-concrete using the transient plane source (TPS) method. Results showed that overall, the thermal conductivity of the concrete was unchanged after the ...
This paper examined the synthesis of hyperbranched polymers (HBPs) and how their hydroxyl end groups help form networks in tannin-based foams. A thermal analyzer (TPS) measured the thermal conductivity of the foam samples using the transient plane source (TPS) method. Results showed that modified foams retained their thermal insulation properties even with the addition of oligomeric precursors. This gives good indication that the addition of hydroxyl-terminated oligomeric precursors to tannin ...
Polyoxymethylene (POM) is a resistant polymer with wide applications in aerospace, automotives, and biomedicine. However, it falls short when used in the manufacturing of sliding parts. In this study, copper particles and polytetrafluoroethylene (PTFE) powder were incorporated into POM to improve the thermal conductivity of the polymer composite while reducing the friction coefficient. A thermal analyzer was used to measure the thermal conductivity of POM composites using the transient plane ...
Researchers in this study aimed to develop polymer composites with high thermal conductivity, using polystyrene (PS) and multi-walled carbon nanotubes (MWNTs). These composites were prepared by ultrasonic radiation, through a simple-solution-evaporation method. Poly(styrene-co-maleic anhydride) (PSMA), with a benzene group and experiencing a strong affinity for PS was used as a base, to allow the MWNTs to be dispersed within the composite (MWNT-g-SMA). Results determined that the addition of MWNTs ...
