Photo-assisted preparation and patterning of large-area reduced graphene oxide–TiO2 conductive thin film

Abstract
A mild photo-assisted reduction method was developed to fabricate large-area, uniform reduced graphene oxide–TiO2 films and micropatterns on various substrates in air at room temperature from a composite insulating film of graphene oxide sheets and TiO2 nanoparticles, with a conductivity (0.5–2 Ω cm) comparable to chemically reduced graphene.
