Composites based on epoxy/graphene oxide (GO) and epoxy/reduced graphene (rGO) were investigated for thermal-mechanical performance focusing the effects of chemical groups present nanoadditive-enhanced surfaces. GO rGO obtained in study have been characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS), powder diffraction (XRD) demonstrating that materials with different oxidation degrees obtained. Thereafter, GO/epoxy rGO/epoxy nanocomposites successfully...
This work has been focused on the one-step fabrication by electrospinning of polyamide 6 (PA6) nanofibre membranes modified with titanium dioxide nanoparticles (TiO2), where these TiO2 aggregates could induce a photocatalytic activity. The main potential application be purification contaminated water.
