Processable, single-layered graphene oxide (GO) is an intriguing nanomaterial with tremendous potential for electronic applications. We spin-coated GO thin-films on quartz and characterized their sheet resistance and optical transparency using different reduction treatments. A thermal graphitization procedure was most effective, producing films with sheet resistances as low as 10(2) -10(3) Omega/square with 80% transmittance for 550 nm light. Our experiments demonstrate solution-processed GO films have potential as transparent electrodes.
可加工的单层氧化石墨烯（GO）是一种极具吸引力的纳米材料，在电子应用方面具有巨大潜力。我们在石英上旋涂了氧化石墨烯薄膜，并使用不同的还原处理方法对其表面电阻和光学透明度进行了表征。热石墨化工艺最为有效，所制备的薄膜表面电阻低至10（2）-10（3）Ω/□，在550nm波长下的透光率为80%。我们的实验表明，溶液处理的氧化石墨烯薄膜有潜力成为透明电极。
