Graphene is 2-dimensional carbon nano sheet which has extraordinary thermal and electric properties. Owing to this characteristics, it has been focused in many researches. In our experiment, stable aqueous dispersion of reduced graphene oxide was simply obtained by reducing GO solution in the presence of poly(4-vinyl pyridine)(P4VP). Its thermal and oxidative stability is answer of why we use P4VP. Our research was analyzed by UV-vis spectroscopy, FT-IR, Photoluminescence(PL) Atomic Force Microscopy(AFM), Environmental Scanning Electron Microscopy(E-SEM), Raman Specstroscopy. |
