Using a solid hot stretching technique, highly-oriented polyoxymethyelen (POM)/multi-walled carbon nanotubes (MWCNTs) composites were created. Thermal properties were analyzed both in the stretched and through-plane directions. Researchers found that by increasing the draw ratio, to as high as 900%, the thermal conductivity of the composite has improved in the stretching direction, when compared to the material prior to this process. Researchers also determined that the thermal conductivity of the MWCNTs ...

In this research article, the thermal conductivity of a polyoxymethylene (POM)/graphite composite was explored. This composite was prepared through an intense process of four intercalation methods; melt, solution, pan milling and in situ intercalation. Graphite is a thermally conductive material, and therefore, it was no surprise when researchers determined that the thermal conductivity of the POM composite increased with the addition of graphite. Thermal conductivity was also noted to ...

Boron Nitride filled epoxy composites are explored on a thermal and mechanical scale within this research article. Researchers took special interest in the effect of filler content, mixing conditions and Boron Nitride agglomerate size, on the thermal conductivity of the composite. Experimental results alluded to an increase in thermal conductivity, as filler content, and mixing speed, time and temperature increased. On the other hand, as the Boron Nitride agglomerate size ...

Catechins were added to boron nitride nanotube (BNNTs)/polyvinyl formal (PVF) composite films, in hopes of further increasing the thermal conductivity of the film. After thermal conductivity testing, the composite films were determined to have an increased thermal conductivity, as compared to their neat form. Researchers determined that the increase of thermal conductivity was related to the aromatic rings within the catechin, which interact with the nanotube surfaces. Upon contact, ...

In this study, researchers set out to determine the effects of embedding self-passivated aluminum fillers, of micro- and nano-meter size and various wt%, into a polyvinylidene fluoride matrix (Al*/PVDF). After testing, the results indicated an increase in thermal conductivity with the introduction of embedded self-passivated aluminum fillers. It was determined that the maximum thermal conductivity possible (3.258 W/mK) was achieved when the ratio of micro- to nano-sized particles was 20: 1, ...
