Solution-phase printing of nanomaterials is a low-cost and effective way to build functional devices. While a multitude of industries have witnessed steady progress in it, the low line resolution remains a challenge for inkjet printing, since the droplet spreading on a substrate inevitably widens the printing tracks. In the present work, a novel embedded printing method based on a liquid viscous film to produce high-resolution lines without a small nozzle (<20 μ m in diameter) or modified substrates was demonstrated. The influences of pre-cured time, substrate velocity and solvent ratio on the diameter of a single droplet and the continuity of multiple droplets were explored. A cylindrical reduced graphene oxide (rGO) line with a diameter of 10 μ m had been deposited on the surface of the viscous liquid substrate and slowly wrapped into polydimethylsiloxane (PDMS) thin film by using a nozzle of 110 μ m in diameter after optimizing the experimental parameters...

通过嵌入均匀液滴印刷提高可拉伸石墨烯基线的线分辨率的新方法

纳米材料的固溶相印刷是一种构建功能器件的低成本有效方法。尽管许多行业都在稳步发展，但低线分辨率仍然是喷墨打印的挑战，因为在基材上散布的墨滴不可避免地加宽了打印范围。在本工作中，展示了一种新颖的基于液体粘膜的嵌入式印刷方法，该方法可在没有小喷嘴（直径<20μm）或没有改性基材的情况下产生高分辨率的线条。探讨了预固化时间，底物速度和溶剂比对单个液滴直径和多个液滴连续性的影响。
