New graphene thermoplastics nanocomposites with improved mechanical, electrical properties and EMI shielding effectiveness

In a prior project, promising results were obtained showing the possibility of using graphene/polymer composites as advanced materials having superior properties than the conventional carbon black loaded polymers. The composites obtained presented electrical conductivities with values of about 10-2 S/m when the percolation threshold was exceeded, an increase of more than 12 orders of magnitude […]

In-situ Exfoliation of Graphene Nanoplatelets Using Supercritical Fluid in Foaming Processing

The manufacturing of high-performance graphene/polymer nanocomposites relies on both the production of high-quality and low-cost graphene sheets and the fine dispersion of graphene in the nanocomposites. The commercial graphene materials in large quantity are typically GnPs with several to tens or even hundreds of graphene layers whose properties are inferior to monolayer graphene. In the […]

Development and characterization of graphene/glass fiber/polyester composites

Polymeric matrices containing nano-size additives have demonstrated remarkable mechanical, electrical, and thermal properties when compared to their micro-composite counterparts. Inserting graphene in a polymer matrix consisting of a glass fiber-reinforced resin is assumed to significantly increase the material electrical conductivity, which is needed in order to fulfill electrical conductivity requirements traditionally met by carbon black […]
