As technology advances, the need for inexpensive polymer-based composites possessing high thermal conductive properties has become more and more important. Previously, the addition of thermal conductive particles, such as alumina, boron nitride and alumina nitride, has caused an increase in the thermal conductivity of the composite. Although an increase in thermal conductivity is present, an increase in fabrication costs is also experienced as a higher quantity of particles is required, ...

The thermal conductivity of heat transfer nanofluids has been determined to increase by 10%, when containing metal oxide nanoparticles and carbon nanotubes. The fluid viscosity of the nanofluids is relatively the same as water, and therefore cannot not account for the increase in thermal conductivity. However, the fashion in which the metal oxide particles conglomerate within the fluid could be a potential explanation for the spike. Results show that under 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 ...

Thermal conductivity measurements of the same samples were carried out using the TPS method. Thermal testing on carbon nanotubes to study for promising fillers. Thermal conductivity of single-walled carbon nanotubes should enable a further reduction in the filler content required for a given enhancement in the composite properties. For the multi-walled carbon nanotube thermal conductivity increased modestly using this method whereas for the single-walled carbon nanotubes the thermal conductivity was ...
