This paper presents the idea of flavonoid foams that are manufactured from natural resources rather than formaldehyde-containing tannin-based foams. A TPS instrument measured the thermal conductivity of the foams using the transient plane source (TPS) technique. Results show that the flavonoid foams are a better choice than tannin-based foams because they have a lower thermal conductivity which makes them more insulative and fire resistant, and they do not release toxic ...
Adding conductive fillers to polymer resins improves the thermal conductivity of the polymers. In this study, Thermocarb TC-300 synthetic graphite and Fortafil 243 carbon fiber were added to Vectra A950RX liquid crystal polymer (LCP) to produce anisotropic single and multiple filler composites. A Thermal Constants Analyzer measured the thermal conductivity of the composites using the transient plane source (TPS) technique. The formulations that contained Thermocarb fillers had higher in- and ...
Paraffin is an excellent phase change material (PCM) for latent heat storage, but it does not efficiently use stored energy because of its low thermal conductivity. In this study, nickel and copper foams were added to paraffin to enhance heat transfer. A Thermal Constants Analyzer measured the thermal conductivity of the paraffin composites using the transient plane source (TPS) method. The addition of copper foam enhanced the thermal conductivity of ...
Porous materials have widespread industrial applications. In this study, mullite materials with porosities between 72-86 vol% were fabricated and a thermal analyzer (TPS) measured their thermal conductivity using the transient plane source (TPS) technique. Results showed that as the porosity of the mullite materials decreased, thermal conductivity increased....
Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. In this study, conductive fillers were added to wax- and polyethylene-based PCMs to improve their thermal conductivity. A Thermal Constants Analyser measured the thermal conductivity of the PCMs using the transient plane source (TPS) method. Results indicated that both nanoparticles improved thermal conductivity, but a lower concentration of expanded graphite improved conductivity more than normal ...
