In this article, researchers set out to determine the thermal characteristics of boron nitride reinforced high-density polyethylene composites. Various filler contents were studied through thermal characterization and it was determined that the composites containing 30% filler elicited the best thermal insulation and mechanical properties. The results displayed that the lower the filler content, the higher the thermal conductivity of the reinforced composite. Researchers also concluded that the smaller the boron nitride ...

The transient plane source sensors were used to measure thermal conductivity and other thermophysical properties of infrared transparent materials, while under infrared imaging. The infrared imaging provided evidence of temperature uniformity and symmetry, as well as temperature monitoring of the sensor and material being tested. The upgraded version of the original TPS system was used including a bridge circuit, a digital voltmeter, and a data analysis module...

The objective of this study was to create polymer composites with high thermal conductivity and mechanical properties. To acquire these, aluminum nitride microparticles were modified with a titanate coupling reagent of isopropyltrioleictitanate, and blended via a power-mixing method into linear low-density polyethylene. Using a thermal constants analyzer, the thermal conductivity of the composite was measured. The results concluded that the addition of aluminum nitride particles to the composite enhanced the ...

This paper highlights the use of the transient plane source (TPS) technique to test the thermal properties of porous building materials, such as autoclaved aerated concrete and calcium silicate boards reinforced by cellulose fibers. Transient methods relay multiple thermophysical parameters, such as thermal diffusivity, specific heat, and thermal conductivity, all in one measurement – a highly sought after trait. Measurements were performed to compare the transient method to other methods of ...

In this study, soft sphere surfactants, with varying head group charges and alkyl chain lengths, were investigated for their effects on the thermal conductivity, rheology, density, contact angle and refractive index of nanofluids. It was noted that the thermal conductivity of the ionic surfactant micelles follows the effective medium theory of poor thermal conductance, with interfacial resistance towards infinity. It was also determined that the longer the alkyl chains on ...
