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, ...

The purpose of this research was to improve the thermal conductivity of boron-nitride filled epoxy composites. To complete this task, the interfacial adhesion in the composite needed to be improved. This was achieved by employing admicellar polymerization to coat the polystyrene and polymethyl methacrylate, on the boron nitride surface. The results indicated an increase in the thermal conductivity of the composite from 1.5 W/mK, with the use of untreated boron-nitride, ...

In this experiment, the thermal conductivity of several composites, with varying matrix composition and boron nitride nanotubes fillers, was investigated. Poly(methyl methacrylate), polystyrene, poly(vinyl butyral) and poly(ethylene vinyl alcohol) were the matrix compositions analyzed. The results indicated that with the addition of the boron nitride nanotube fillers, there was a 20-fold increase in the thermal conductivity of the polymer. Several other properties were analyzed alongside of thermal ...

Researchers have determined the potential of increasing the thermal conductivity of insulating polymers by adding conductive fillers. One common application this may be used for, is fuel cell bipolar plates. In this article, researchers tested varying amounts of three different carbon fillers (black carbon, synthetic graphite particles, and carbon nanotubes), by adding them to polypropylene. Both single fillers and combination fillers were studied for their potential effects on the thermal ...

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, ...
