In order to prepare more thermally resistant materials for use as thermal barrier coatings, the authors performed experiments on yttrium stabilized-zirconia (7YSZ) in order to investigate sintering resistance and phase stability at high temperatures. It was theorized that the main factor that affected the sintering resistance and phase stability at high temperatures was the concentration of impurities (Al2O3 and Si2O) present in the 7YSZ. Therefore in this report ...
A one step polymer-incorporation sol-gel process coupled with a surface modification and ambient pressure drying process was developed to synthesize silica-poly(vinylpyrrolidone) composites aerogels. The properties that were investigated were: hydrophobicity, mechanical strength and thermal conductivity at high temperatures. The authors envisioned the use of these polymer composites in energy saving areas with large scale production....
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 ...
