Graphene reinforced UV-curable epoxy resins: Design, manufacture and material performance

•Graphene and its derivatives improve mechanical properties of polymers.•Potentiality of graphene and its derivatives in terms of their anti-scratch performance.•Reduced graphene oxides functionalised with amino-propyl triethoxy silane (APTES).•UV curable epoxy coatings covalently bond to amino-functionalised silica-nanoparticles.•APTES-functionalised reduced-graphene oxide reduces scratch visibility.
