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

The experimental analyses involved FT-IR spectroscopy to study the chemical interactions that occurred among the different compounds in the investigated mixtures, progressive and constant load scratch tests and SEM images of the residual scratch patterns to evaluate the micro-mechanical response and scratch visibility of the coatings. APTES-functionalised reduced-graphene oxide was found to be able to reduce the scratch visibility, thus revealing its suitability to promote the effective anti-scratch properties of UV-curable bis cyclo-aliphatic epoxy resins deposited on polycarbonate.
