Minerals are often added to polypropylene (PP) foams to improve thermal conductivity. The aim of this study was to test and compare the thermal conductivity of unfilled, magnesium hydroxide (Mg(OH)2)-, and montmorillonite (MMT)-reinforced PP foams. An analyzer measured the thermal conductivity of the polypropylene foams using the Transient Plane Source (TPS) method. Results showed that thermal conductivity increased with foam density and with magnesium concentration....
Nanoparticle-enhanced phase change materials (NePCMs) are nanofluids that can be used for thermal energy storage when they undergo solid-liquid phase transitions. In this study, a Thermal Constants Analyzer (TPS) measured the thermal conductivity of eicosane-based NePCM samples using the transient plane source (TPS) method. Results showed that thermal conductivity of the solid composites increased with temperature, and eicosane-CuO samples that solidified in an ice-water bath had the lowest thermal conductivities, ...
Nano-inclusions are thermally conductive particles that improve the thermal conductivity of liquid mediums. In this paper, the thermal properties of Mg2Si were evaluated after the addition of TiO2 nanoparticles. An instrument measured the thermal conductivity of the nanofluid using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluid was the highest at lower temperatures, and did not improve with the addition of the ...
A nanoparticle-enhanced phase change material (NePCM) is prepared by the dispersal of carbon nanotubes in 1-dodecanol. The objective of this experiment was to determine if the addition of nanoparticles could increase the thermal conductivity of the base PCM while resulting in a NePCM that would still have the required properties of a functional PCM. It was found that the thermal conductivity was enhanced through the addition of the carbon nanotubes; ...
Polyether Ether Ketone (PEEK)/hexagonal boron nitride (h-BN) nanocomposites were formed by a planetary ball milling process and hot compression molding in order to determine the effect of the addition of h-BN on the properties of PEEK. In particular, the tensile strength, friction and wear behaviors, morphology, hardness, thermomechanical properties, and thermal conductivity of the nanocomposite were examined. Hexagonal boron nitride was added in filler concentrations of up to 5 wt. %. ...
