제목 Plasticized polymer interlayer for low temperature fabrication of a high-quality silver nanowire-based flexible transparent and conductive film
초록 Silver nanowires (AgNWs) are one of the most promising materials for flexible transparent conductive films (TCFs) to replace commercial indium tin oxide (ITO); however, there are still numerous problems originating from poor AgNW junction formation and improper AgNW embedment into transparent substrates. To mitigate these problems, high temperature processes have been adopted; however, unwanted substrate deformation can occurred. In this work, we present a novel poly(methyl methacrylate) (PMMA) interlayer plasticized by polyethylene glycol (PEG) to achieve a low temperature fabrication of AgNW-based TCF, which does not cause any substrate deformation. By exploiting the viscoelastic property of the plasticized interlayer, the monolithic junction and embedment of AgNWs into the interlayer are achieved in a single-step pressing. Moreover, we can obtain thermal-stability by extracting PEG. The resulting AgNW TCFs are highly transparent, highly conductive, and environmentally robust.
