提出了一种利用喷墨印刷技术制备柔性透明金属网格导体的有效方法。在这个系统中，银纳米粒子（AgNPs）的喷墨打印直接组装成双行柔性聚（对苯二甲酸乙二醇酯）基板上，随后在室温下烧结。利用这种方法，成功地制备了线宽为5-6 μm的高柔性、高透明AgNPs栅基导体。透射率达到93.6%，薄层电阻小于30 Ω sq-1。这种简单、成本效益高且非光刻的方法改进了当前用于产生图案化微结构的制造方法，并且具有很大的潜力来定制用于光电器件的制造。
An effective and facile strategy was developed to fabricate a flexible transparent metallic grid conductor based on the coffee ring effect with an inkjet printing technique. In this system, silver nanoparticles (AgNPs) were ink-jet printed to directly assemble into twin lines on flexible poly(ethyleneterephthalate) substrates and subsequently sintered at room temperature. Taking advantage of this approach, a highly flexible and transparent AgNPs grid-based conductor was successfully fabricated with a line width of 5–6 μm. The transmittance reached 93.6%, and the sheet resistance was less than 30 Ω sq−1. This simple, cost-effective and non-lithographic approach improves the current fabrication approaches for the creation of patterned microstructures and has great potential to be tailored for the fabrication of optoelectronic devices.
