(A) Photographs of large EOG film. This film was prepared by pouring the EOG water suspension into a teflon mould and then dried. (B) The electrical resistance of the EOG film measured with a hand-held multimeter. It shows an electrical resistance of 23.9 Ω. (C) Photographs of GO (left) and EOG (right) films before (a) and after (b) thermal annealing at 800°C. (D) Photographs of transparent EOGN films deposited on silica slice. These films were prepared by vacuum filtration of EOGN toluene dispersion onto mixed cellulose ester membrane and then transferred to a silica slice by dissolving away the ester membrane in acetone. (E) Optical transmittance of EOGN film with calculated thickness. (F) Resistance of the EOGN films vs. the thermal-annealed EOGN transmittance at 550 nm.
