We present the reduction of solution processed graphene oxide films by hydrogen iodide vapor. The films were studied by Raman spectroscopy and Fourier-transform infrared spectroscopy and its optoelectronic properties characterized. We obtained reduced graphene oxide films on polyethylene terephthalate flexible substrates with good electrical properties, 3.74×10 Ω·m, and high optical transmittance of 70% in the visible range. The fabricated layers contain graphene sheets with sizes up to ∼10 μm long and ∼6 μm wide. The presented solution, with highly concentrated processed graphene oxide, could be used as printing ink for manufacturing transparent and conductive electrodes on plastic substrates without the requirement of elevated temperatures.
我们展示了通过碘化氢蒸汽对溶液处理的氧化石墨烯薄膜进行还原。通过拉曼光谱和傅里叶变换红外光谱对这些薄膜进行了研究，并对其光电特性进行了表征。我们在聚对苯二甲酸乙二醇酯柔性基板上获得了具有良好电学性能（3.74×10 Ω·m）和可见光范围内70%高光学透过率的还原氧化石墨烯薄膜。所制备的层包含尺寸长达约10μm、宽约6μm的石墨烯片。所提出的含有高浓度处理过的氧化石墨烯的溶液，可作为印刷油墨用于在塑料基板上制造透明导电电极，而无需高温条件。
