In this paper, we fabricate Epoxy/ZnO-GO composite films using photoinduced cationic ring opening polymerization processes with self-cleaning ability and improved thermal properties under the photo exposure. The presence of ZnO nanoparticles on the GO surface aids in achieving good self-cleaning properties by removing model dirt, methylene blue, (within 1-2 h) under sunlight. An increase of almost 15 ℃ in the thermal stability was obtained by introduction of 0.6 wt% ZnO-GO to the epoxy matrix. Therefore, the nanocomposite could be a promising futuristic material for many advanced applications and used as a surface coating material where it can remove the presence of organic dirt and provide a clean surface.
