Oxidized few layers of graphene for the assembling of nano-micelles for the celaning of the black crust from peperino substrata

In this work, few layers of functionalized graphene nanoribbons (FLGs) have been synthesised, using the unzipping oxidative reaction, from SWCNTs, used here as graphene precursor. After a full characterization study (under a topographic and structural point of view), FLGs nano-micelles, assembled using Tween20, as working medium, have been also applied on the selected artwork surfaces (affected by the environmental alterations) as new cleaning strategy. In particular, the cleaning efficiency of the FLGs, as nano-carrier, to release, in a controlled way, the cleaning agent (i.e.; the surfactant agent, Tween20) has been evaluated, and the corresponding performances were presented.
