Abstract
We report a clean, facile, and fast transfer method for uniform and ultrathin graphene oxide (GO) films. Using vacuum filtration, we make the GO film with less 5 nm thicknesses transfer to the target substrates (silicon oxide, glass, PET, PI) and bend surfaces by vaporizing pressure of hot water. The quality of a transferred GO film is characterized by optical microscopy, atomic force microscopy, scanning electron microscopy, Raman spectroscopy, and we demonstrate the successful transfer of GO films without defects on a film and residuals on a supporting membrane. We also demonstrated that GO films coated substrates exhibit improved anti-scratching properties and controlled hydrophilicity over non-coated substrates.
