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 ...
The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on the treatment method used. The dependence of thermal conductivity on temperature was also studied and it was found that the maximum thermal conductivity was at ...
In order to measure the thermal properties of polymer composites that are filled with ceramic powder the researchers created 'macromodels' that accurately modelled the interfacial resistance at each ceramic-polymer boundary. The macromodels were created by spin-coating the polymers onto sapphire wafers....
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 ...
