As technology advances, improving the efficiency of heat dissipation by thermal adhesives in electronic devices is becoming increasingly important. In this study, a thermal constants analyzer measured the thermal conductivities of eight different epoxy resin thermal adhesives using the transient plane source (TPS) method. Results showed that the layer-structure fillers enhanced the thermal conductivity of the epoxy matrix the most, while the sharp corner-shaped fillers had the lowest impact on ...
The authors outline a method of enhancing the thermal properties of a paraffin phase change material through the addition of herringbone-style graphite nanofibers (HGNFs). It was found that the solid-phase thermal conductivity increased exponentially with the presence of HGNFs; however, a significant increase in the liquid-phase thermal conductivity was not observed until the concentration of HGNFs in the composite PCM reached a point above the percolation threshold. The volumetric heat ...
Various microfibrillar composites were prepared in situ using boron nitride as a thermally conductive filler. The multistage stretching extrusion process was used in an effort to improve thermal conductivity and mechanical properties. It was found that the addition of laminating-multiplying elements (LMEs) improved the dispersion of BN in the composite polymers and they also improved the tensile and impact strength of the polymers. It was also found that the thermal ...
Hexagonal boron nitride (h-BN) was used as filler in varying concentrations to form composite polymers with polyactic acid, polyamide, and polyphenylene sulfide. The objective of this work was to produce a composite polymer with a high thermal conductivity for use as electronics packaging. It was determined that although thermal conductivity increased with increasing filler content, it was not necessarily due to the increased number of filler particles present, but rather ...
Recycled tyre rubber was used to replace varying fractions of limestone as filler in asphalt in order to determine the effect that the added rubber would have on the thermal and physical properties of the asphalt. The properties of interest were the penetration, soft point, and ductility of the asphalt binder, as well as the moisture sensitivity, thermal conductivity, thermal diffusivity, and volumetric thermal capacity of the asphalt mixtures. It ...
