Three different carbons (carbon black, synthetic graphite particles and carbon fiber) were added to Vectra A950RX Liquid Crystal Polymer in order to synthesize different composites for use in fuel cells. The carbon fillers were used individually and also in combination with other carbon fillers. A TPS was used to measure the thermal conductivities of the synthesized composites. It was found that the use of synthetic graphite particles as the ...
Through the use of thermally conductive fillers the thermal properties of polystyrene (PS) are improved significantly. The different fillers include: aluminum oxide (Al2O3), magnesium oxide (MgO), B-silicon carbide particles (B-SiCp), and B-silicon carbide whiskers (B-SiCw). The use of PS flakes resulted in higher thermal conductivities than the use of PS particles, and the use of B-silicon carbide whiskers resulted in the most favorable thermal conductivity and resulted in a ...
This study looked at the use of two different fillers to improve the thermal properties of an epoxy resin. The two fillers were multi-walled carbon nanotubes (MWCNTs) and aluminum nitride (AlN). Through the use of poly(glycidyl methacrylate) (PGMA) and a zirconate coupling agent the MWCNTs and AlN particles respectively were added to the epoxy resin. Through the use of 1 vol.% MWCNT and 25 vol.% AlN the researchers were able to ...
Five different glasses were created in the present study with varying compositional ratios in a CaO-B2O2-SiO2 (CBS) System and the thermal and dielectric properties of these glasses were studied. A glass was found that had high thermal conductivity and promising dielectric properties, with a low sintering temperature that allows for the addition of fillers to adjust thermal and dielectric properties further....
The authors observed a remarkable synergistic effect when they used multi-graphene platelets (MGPs) and multi-walled carbon nanotubes (MWCNTs) together in an epoxy composite. The use of these two fillers together increased the tensile strength, thermal conductivity, solubility and compatibility relative to the various individual components. The 1D nanotubes inhibit the aggregation/stacking of the platelets and thus result in high contact area between MGP/MWCNT and the polymer matrix....
