Abstract
The inventive method for applying a protective graphene coating onto a surface, especially onto a two- or three dimensional artwork or colored surface, comprises the following steps: a) depositing, preferably by chemical vapor deposition (CVD), graphene onto a at least one side of a supporting substrate to produce a graphene/substrate composite including a continuous graphene membrane formed on at least one side of said substrate; b) removing the substrate, or lifting off the graphene from the substrate and c) depositing the graphene membrane onto the surface. A protective graphene coating prepared and deposited by this method provides protection for a surface, especially a two- or three-dimensional artwork or a colored surface, against color degradation, especially fading, yellowing and discoloration due to exposure to UV radiation, dirt, dust, moisture, chemical and/or oxidizing agents.
