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 ...

During a melt blending process, carbon nanotubes (CNTs) were added to a poly(vinylidene fluoride)/Boron nitride (PVDF/BN) composite, to increase the thermal conductivity of this polymer composite, for uses in the electronic industry. After this process, the thermal and electrical conductivities, along with any microstructure changes were investigated. It was determined that with the addition of CNTs, the thermal conductivity rating of the composite increased, as well as ...

The need for higher thermal conductivity fillers, such as aluminum nitride, to deal with an increase in the heat output from future semiconductors has arisen, as most of them are now packaged in a silica epoxy polymer composite. Thermal conductivity testing was performed on the aluminum nitride composite using a thermal constants analyzer and the highest reading was 3.39 W/mK, approximately 15 times higher than pure epoxy. Based on the results, ...

In this article, researchers studied the effect of particle shape on the thermal conductivity of copper reinforced polymer composites. Short-fiber shaped polyamide composites with filler content ranging from 0 to 30 % were measured, alongside of polyamides containing 0 to 60 % filler, shaped as spheres and plates. When the filler content is low, particles are not interacting with each other, and therefore the thermal conductivity is low. As the filler percentage increases to 10%, an immediate ...
