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 the epoxy matrix. Therefore, in samples with a higher oxygen content, a higher interfacial contact area is present between the organic and inorganic phases in ...
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 permeability in comparison to electroactive polyimide membranes....
The purpose of this study was to fabricate and analyze the physical properties of polyacrylate–gold nanocomposites (PGNs) with gold nanoparticles (GNPs) as their nucleation agents. The transient plane source (TPS) method was used to measure the thermal properties of the polyacrylate–gold nanocomposite foams (FPGNs) and PGNs. Results showed that the addition of GNPs improved thermal conductivity of the PGN materials, but as the size of GNPs increased, the ...
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....
