Thermal interface materials based on carbon nanotubes and their thermal characterization

The effects of using different fillers and the effects of filler content and particle size on the thermal properties of thermal interface materials were investigated. The most prominent enhancement in thermal conductivity was observed for samples containing carbon nanotubes and graphite. The filler particle size was also found to significantly affect the thermal conductivity, as smaller fillers resulted in a higher thermal conductivity. The article also describes two sample holders ...

Improvement of Soft Tooling Process Through Particle Reinforcement with Polyurethane Mould

In the soft tooling process for making moulds, polyurethane is often used as a flexible mould material. The low thermal conductivity of polyurethane results in a long solidification time of the wax/plastic pattern produced in the soft tooling process. In an effort to address this issue, the authors of this article have added highly conductive fillers to polyurethane. The fillers used for this study were aluminum fine powder and ...

Thermal Conductivity Measurements in Nanofluids via the Transient Planar Source Method

The transient plane source (TPS) method was used to measure the thermal conductivity of automotive coolants, as well as equivalent nanofluids to these coolants. The results of the study indicated that the TPS was able to accurately measure the thermal conductivity, with an error of between 2 and 4%....

CO2-blown microcellular non-isocyanate polyurethane (NIPU) foams: from bio- and CO2-sourced monomers to potentially thermal insulating materials

Low-density microcellular non-isocyanate polyurethane (NIPU) foams were prepared using biological compounds and carbon dioxide. The morphology of these foams was investigated by scanning electron microscopy (SEM), and the thermal conductivity was determined using the transient plane source (TPS) method. It was concluded that a study needed to be undertaken to determine how to fine tune the morphology of the foams in order to decrease the thermal conductivity of the foams....

Cleaner production of the lightweight insulating composites: Microstructure, pore network and thermal conductivity

A porous matrix was prepared using low-density sawdust and a metakaolin-based geopolymer paste. The matrix was prepared in order to evaluate its performance as a thermally insulating building envelope. The matrices that had approximately 4 MPa of bi-axial four points flexural strength were prepared in a ratio of geopolymer paste:sawdust of between 1:1 and 1:1.5, and the thermal conductivity of these matrices was between 0.2-0.3 W/m·K....
