Chemical approach like functionalization of graphene oxide (GO) and reduced graphene oxide (rGO) is crucial for various applications. In particular, tailor-made functionalization of graphene can supply physicochemical and electronic properties that we want to realize. In this talk, I introduce recent research results on functionalization and applications of GO and rGO. First, I demonstrate new approach for fabrication of GO and rGO multilayers which can be a building block for various hybrid films with 0 or 1 dimensional nanomaterials. This was achieved by using layer-by-layer (LbL) assembly of positively and negatively GO sheets which could provide highly controllable thin films in terms of thickness, transmittance, and sheet resistance. Another interesting thing is an integration of graphene and functional materials via covalent and non-covalent interaction. I introduce the assembly of rGO and fullerene (C60) into core/shell hybrid nanowires by employing the liquid-liquid interfacial precipitation (LLIP) method. C60 nanowires are first formed and then rGO sheets are coated on surfaces of them. The structural characterization of the rGO/C60 nanowires and their applications for field-effect transistors and photovoltaic solar cells are introduced in this presentation. Lastly, I introduce functional hybrid films of rGO sheets with metal nanoparticles which are very promising for highly efficient and transparent counter electrodes of dye-sensitized solar cells.
