In this Letter, a novel method for the preparation of surface modified graphene oxide (GO) sheets is proposed, by the vaporization of amino-functionalized polyhedral oligomeric silsesquioxanes (POSS) on the GO sheets. The chemical composition, surface morphology as well as the surface properties of the prepared films were investigated by means of Fourier transform infrared spectroscopy, water contact angle measurements and field emission electron microscopy. When exposed to visible light the film obtained by grafting the amino-functionalized POSS on GO sheets showed a photoconductivity response. (C) 2012 Elsevier B.V. All rights reserved.
