A team of researchers from the Institute of Chemical Engineering Sciences of Foundation for Research and Technology-Hellas (FORTH/ ICE-HT), the Department of Chemical Engineering of the University of Patras, and the Center for Colloid and Surface Science (CSGI) of the University of Florence, led by Professor Costas Galiotis, set out to use ‘graphene veils’ for the protection of paintings against environmental degradation.
The exposure of colors used in artworks to ultraviolet (UV) and visible light in the presence of oxidizing agents, triggers color degradation, fading and yellowing. These degradation mechanisms can lead to irreversible alteration of artworks, which consist of a valuable heritage for humankind. Currently used protective varnishes and coatings are often problematic, as their removal requires the use of solvents, which can adversely affect the underlying work surface.
