印刷电子由于其低成本和生产率而成为新兴技术之一。最近，许多研究人员试图将印刷技术应用于在柔性基板上制造精细的电子图案，包括薄膜晶体管的栅极线。在这项研究中，我们制作了一个灵活的铅版使用纳米压印工艺，并将其用于反向胶印。然后，我们分析了压印铅版的表面能对工艺参数，如印刷速度和滚动方向的影响。结果表明，通过控制铅版的表面能，可以显著提高工艺的生产率和印刷图案的质量。当使用表面能与橡皮布的表面能显著不同的树脂制造柔性铅版时，油墨可以容易地分离，并且可以成功地雕刻精细图案，而不管图案形状如何。
Printed electronics is one of the emerging technologies owing to its low cost and productivity. Recently, many researchers tried to adapt printing technology to the fabrication of fine electronic patterns on flexible substrates, including the gate line of thin film transistors. In this study, we fabricated a flexible cliche using the nanoimprint process and used it in reverse offset printing. Then, we analyzed the effect of the surface energy of the imprinted cliche on process parameters, such as printing speed and rolling direction. We showed that the productivity of the process and quality of printed pattern can be considerably enhanced by controlling the surface energy of the cliche. When a flexible cliche is manufactured using a resin with a surface energy considerably different from that of the blanket, the ink can be detached easily and fine patterns can be engraved successfully regardless of the pattern shape.
