Fluorescent epoxy-graphene quantum dots nanocomposites: synthesis and study of properties

ABSTRACT This study aims to investigate the reinforcing effects of graphene quantum dots on various properties of epoxy resins. To do this, graphene quantum dots were synthesized, then, characterized by various spectroscopic methods. These nanoparticles including several weight percentages along with a curing agent were added to epoxy resin. Finally, fluorescent epoxy graphene quantum dots nanocomposites were prepared. FTIR, photoluminescence, UV-visible absorption, FESEM, TGA, tensile testing and DMTA analysis were used to characterize the resultant nanocomposites. Findings evinced that adding graphene quantum dots to the epoxy resin led to an improvement of thermal stability, mechanical features, and viscoelastic properties of nanocomposites. Graphical abstract
