Reduced graphene oxides (RG-Os) have attracted considerable interest, given their potential applications in electronic and optoelectronic devices and circuits. However, very little is known regarding the chemically induced reduction method of graphene oxide (G-O) in both solution and gas phases, with the exception of the hydrazine-reducing agent, even though it is essential to use the vapour phase for the patterning of hydrophilic G-Os on prepatterned substrates and in situ reduction to hydrophobic RG-Os. In this paper, we report a novel reducing agent system (hydriodic acid with acetic acid (HI-AcOH)) that allows for an efficient, one-pot reduction of a solution-phased RG-O powder and vapour-phased RG-O (VRG-O) paper and thin film. The reducing agent system provided highly qualified RG-Os by mass production, resulting in highly conducting RG-O(HI-AcOH). Moreover, VRG-O(HI-AcOH) paper and thin films were prepared at low temperatures (40 °C) and were found to be applicable to flexible devices. This one-pot method is expected to advance research on highly conducting graphene platelets.

鉴于其在电子和光电器件和电路中的潜在应用，还原氧化石墨烯 (RG-O) 引起了相当大的兴趣。然而，除了肼还原剂之外，对于溶液和气相中氧化石墨烯 (GO) 的化学诱导还原方法知之甚少，尽管使用气相进行亲水性图案化是必不可少的。预图案化基板上的 G-Os 和原位还原为疏水性 RG-Os。在本文中，我们报告了一种新型还原剂系统（氢碘酸与乙酸 (HI-AcOH)），该系统可以有效地一锅还原溶液相 RG-O 粉末和气相 RG-O（ VRG-O) 纸和薄膜。还原剂系统通过量产提供高品质的RG-Os，导致高度导电的 RG-O(HI-AcOH)。此外，VRG-O（HI-AcOH）纸和薄膜在低温（40°C）下制备，并被发现适用于柔性设备。这种一锅法有望推进对高导电石墨烯片的研究。 |
