我们报道了一种简单的技术，用于图案化和转移银纳米线（AgNWs）到各种基板上。通过仅采用UV/O-3和蒸汽处理的六甲基二硅氮烷（HMDS），我们能够准确地操纵表面能通过交替的末端基团的聚二甲基硅氧烷（PDMS）基板，以协助选择性形成和剥离的AgNW膜。在PDMS上进行简单的UV/O-3处理能够在旋涂后实现AgNW的均匀、良好限定和高导电图案。HMDS的气相处理降低了氧化的PDMS的表面能，使得嵌入环氧树脂（EPR）中的图案化AgNW从PDMS干净地转移到目标衬底。结果表明，AgNW-EPR/PET复合材料在弯曲试验、胶带试验、水中超声处理、化学溶剂浸泡等条件下均表现出良好的耐久性。此外，我们证明了AgNW-EPR复合材料的工作以及氧化的PDMS，聚乙烯醇（PVA），纸张和曲面玻璃上的导电图案。该方法简单易行，扩展了AgNW在电子领域的应用范围，并有可能应用于其他纳米材料。
We report a facile technique for patterning and transferring silver nanowires (AgNWs) onto various substrates. By employing only UV/O-3 and vapor treatment of hexamethyldisilazane (HMDS), we are able to accurately manipulate the surface energy via alternating the terminal groups of a polydimethylsiloxane (PDMS) substrate, so as to assist selective formation and exfoliation of AgNW films. A simple UV/O-3 treatment on PDMS enables uniform, well-defined, and highly conductive patterns of AgNWs after spin-coating. A vapor treatment of HMDS lowers the surface energy of the oxidized PDMS so that the patterned AgNWs embedded in an epoxy resin (EPR) are cleanly transferred from the PDMS to the target substrate. It is found that the AgNW-EPR composite on polyethylene glycol terephthalate (PET) exhibits remarkable durability under the bending test, tape test, ultrasonic treatment in water, and immersion of chemical solvents. In addition, we demonstrate that the AgNW-EPR composite work well as conductive patterns on the oxidized PDMS, polyvinyl alcohol (PVA), paper, and curved glass. The facile technique extends the applicability of AgNWs in the field of electronics, and it is potentially applicable to other nanomaterials.
