Epoxy nanocomposites containing thermally reduced graphene oxides (TRGs) with different oxygen contents were prepared and their mechanical and thermal properties were investigated. It was found that increasing the number of oxygen containing groups on the TRGs resulted in reduced agglomeration of the graphene oxides within ...
Porous epoxy thermosets were prepared using poly(ethylene glycol) (PEG) as a template. The two epoxies that were used to make the porous thermosets were diglycidylether bisphenol-A (DGEBA), and triphenylolmethane triglycidyl ether (TGTPM). Trimethylolpropane tris(poly(propylene glycol)), amine terminated)ether (T-403) was used as ...
The thermal imidization method was used to prepare an electroactive polyimide/graphene nanocomposite (EPGN) material membrane. It was determined that the composites that were formed had improved mechanical strength, thermal stability, and thermal conductivity, as well as an improved dielectric constant and a decreased gas ...
PMMA/silica mesocomposites (PSM) and nanocomposites (PSN) were synthesized by incorporating vinyl-modified mesoporous silica (VMS) or silica particles into the poly (methyl methacrylate). The prepared composites were characterized by TEM and GPC. Thermal conductivity and gas permeability measurements were performed on the composites using a ...
This research studied the effect of the addition of vinyl-modified silica and raw silica additions to polymer-silica nanocomposite foams. Extensive physical property characterization was undertaken after their addition to quantify their influence. TEM found that silica particles added through the vinyl-modified silica dispersed better than ...
