透明导电薄膜在现代电子领域有着非常广泛的应用.我们利用简单的液面沉积法在柔性基底PET上成功制备了氧化石墨烯薄膜，在室温下经过碘化氢(HI)蒸汽还原后得到石墨烯透明导电薄膜.利用各种表征手段(SEM、TEM、AFM、吸收光谱(UV-Vis)和电阻分析(四探针法))系统的研究了不同沉积层数的石墨烯薄膜的透光性和导电性之间的关系：随着石墨烯沉积层数的增加，导电薄膜的导电性上升，但薄膜的透光率下降.在透光率(λ＝550 nm)为82．22％时，导电薄膜的方块电阻为620Ω/□.
Transparent conductive film are widely used in electronics industry.Here we reported the Graphene oxide thin films were prepared on flexible substrates PET by liquid deposition method,the graphene transpar-ent conductive film were achieved after hydrogen iodide (HI)vapour reduction at room temperature.Several kinds of characterization (including SEM,TEM,AFM,UV-Vis and resistance analysis (four-probe method)) were employed to study the relationship between transmittance and conductivity with different deposited layers of graphene films.The results show that the conductive of the graphene film will be increased with the more layers of deposited graphene,but the light transmittance of films decreased.The conductivity of the graphene transparent film was 620 Ω/□ with 82.22% in light transmittance (λ=550 nm)were achieved.
