Achieving excellent quality printing of graphene oxide is highly demanded in superior performance device fabrication. Laser-induced forward transfer (LIFT) is a promising method for printing low viscosity liquids, which alleviates the restrictions regarding the rheological properties and the size of the particles suspended in the printing ink. However, the investigation of GO printing is very limited, and this procedure still suffers from low quality and reproducibility. Herein, an effective approach of printing reproducible and well-defined GO droplets through LIFT was presented. Laser ablation was used to create a few microns deep cavity on the microscope glass, which led to the superhydrophilicity of the ablated surface and helped in the formation of a uniform GO film. Subsequently, droplet printing using LIFT method with the modified donor substrate and various pulse energies was investigated. Droplets with a relatively circular shape and limited debris were successfully printed. The droplet diameter grew linearly from 40 to 165 μm with the increasing pulse energy from 4 to 11 μJ. Finally, LIFT of GO with the cleaned donor substrate was studied, and the repetitive printing results showed the feasibility of reusing the modified donor substrate.

在性能优异的器件制造中，对获得高质量的氧化石墨烯印刷有很高的要求。激光诱导正向转移（LIFT）是一种用于印刷低粘度液体的有前途的方法，它减轻了有关流变性质和悬浮在印刷油墨中的颗粒尺寸的限制。然而，GO印刷的研究非常有限，并且该过程仍然存在质量低和可再现性的问题。在这里，提出了一种有效的方法，通过LIFT打印可重现和轮廓分明的GO液滴。激光烧蚀用于在显微镜玻璃上形成几微米深的空腔，从而导致烧蚀表面具有超亲水性，并有助于形成均匀的GO膜。随后，研究了使用改进的施主基板和各种脉冲能量的LIFT方法进行的液滴打印。具有相对圆形形状和有限碎屑的液滴已成功打印。液滴直径从40增至165μm线性增长，脉冲能量从4增至11μJ。最后，用清洁的供体基材对GO的LIFT进行了研究，重复打印结果表明了重复使用改性供体基材的可行性。
