The authors prepared PMMA/clay composites by the in situ bulk polymerization method. The prepared composites were characterized by FT-IR, WAXRD, SEM, TEM, DMA and the transient plane source (TPS) technique to measure thermal conductivity. Not only were the thermal properties of the composites studied, but physical and chemical properties as well....
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 analysis of a pultruded E-glass reinforced polyester (GFRP) composite is performed by TGA, DSC and DMA methods. The data obtained from these analysis methods agreed well with theoretical models applied to the GFRP. The specific heat capacity of the composite was found to decrease over heating and the decomposition process....
