传统印刷值得重新审视，因为它在满足制造印刷电子产品，3D产品等方面的需求激增方面已经建立了程序，但是，将印刷渗透到这些领域的一个目标是在不限制润湿性的情况下控制图案转移。在这里，我们介绍了一种可混溶的液-液转移印刷机制，该机制可以同步材料制备和材料图案化，具有所需的特性，包括无限的原材料选择，耐腐蚀性，无润湿约束，以及为多功能应用制备大面积无缺陷材料的能力。理论建模和实验表明，供体液体可用于在受体材料的本体内形成图案，从而允许获得的固有图案化的功能材料耐受苛刻条件。与目前的液体打印技术不同，这种打印方法可以实现稳定和无缺陷的材料制备，预计将在柔性显示器，软电子，4D打印等领域中发挥作用。
Conventional printing is worth revisiting because of its established procedures in meeting the surging demand of manufacturing printed electronics, 3D products, etc. However, one goal in penetrating printing into these is to control pattern transfer with no limitation of wettability. Here we introduce a miscible liquid-liquid transfer printing mechanism that can synchronize material preparation and material patterning with desirable properties including limitless selection of raw materials, corrosion resistance, no wetting constraint, and ability to prepare large-area defect-free materials for multi-function applications. Theoretical modeling and experiments demonstrate that donor liquid could be used to make patterns within the bulk of a receiver material, allowing the obtained intrinsically patterned functional materials to be resistant to harsh conditions. Different from current liquid printing technologies, this printing approach enables stable and defect-free material preparation and is expected to prove useful in flexible display, soft electronics, 4D printing, and beyond.
