The authors present a review of the thermal properties of graphene, and present one example of a practical application of graphene in thermal management, as an additive to phase change materials. It was found that the use of liquid-phase-exfoliated graphene as a filler in phase change materials has potential to enhance the thermal management in high-power battery packs. The results also indicated that graphene had the ...
The authors have presented a study on the effect of interface thermal resistance on thermal conductivity in carbon nanofiber (CNF) composites. Upon measuring the thermal conductivities of nanocomposites with varying filler concentrations, it was found that the measured thermal conductivities were much lower than those predicted for a nanocomposite in which thermal resistance at CNF-matrix interfaces was negligible. A computational study on interface thermal resistance was then performed. It was ...
In an effort to become more sustainable, the construction industry has been looking for ways to use less new raw materials by making use of waste by-products from industrial applications. In this study, nano-crystalline aluminum sludge was added as a filler to clay bricks. The hope was that this would not only be an environmentally friendly product, but that it would also improve the thermal properties of the bricks. The ...
Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use them as hosts for phase-change materials. It was found that using graphite powder with smaller particle sizes resulted in foams with a higher bulk density than those prepared with an equal amount of larger graphite particles, this increased density resulted ...
Sulfonated polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SPSPB) was used as a polymer matrix to create polymeric nanocomposites using graphite (G) and graphite-polyoxometalate (G-POM) as fillers. It was found that the nanocomposites had higher thermal and electrical conductivities than SPSPB alone, and that both the thermal and the electrical conductivity increased with increasing filler concentration. At all filler contents tested, the SPSPB/G-POM had both a higher thermal conductivity and a higher electrical ...
