Thermally Exfoliated Graphite Oxide (TEGO) was mixed with natural rubber (NR) using a two-roll mill but the mixing of the TEGO with the NR didn't proceed as expected. Therefore the researchers had to modify the procedure and decided to pre-mix the TEGO and NR in an ultrasonically-assisted latex co-coagulation process followed by two-roll milling resulted in significant improvement in the thermal and electrical properties of the nanocomposite compared to the ...
A series of polymer-matrix composites were synthesized by using a variety of carbon nanotubes (single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs) and multi-walled carbon nanotubes (MWCNTs)) and a polymer matrix (either polystyrene (PS) or poly(methyl methacrylate) (PMMA)). Different surfactants and polymerization methods were also used in order to generate a wide range of different composites. These different composites were all tested for thermal and electrical conductivity and characterized ...
As electronic devices become smaller, power densities increase and so do hotspot temperatures, leading to a need for materials that can exchange heat better. The materials that facilitate this heat exchange are called thermal interface materials (TIMs). Graphene has been shown to demonstrate superior thermal conductivity and a particular form called few-layer graphene (FLG) was used in this project. A novel TIM was created by the mixing of a silver ...
