We propose a versatile yet practical transferring technique to fabricate a high performance and extremely stable silver nanowire (AgNW) transparent electrode on arbitrary substrates. Hydroxylated poly(ethylene glycol) terephthalate (PET) or poly(dimethylsiloxane) (PDMS) deposited with AgNWs was selectively decorated to lower its polar surface energy, so that the AgNWs were easily and efficiently transferred into an epoxy resin (EPR) as a freestanding film (AgNWs-EPR) or onto various substrates. The AgNWs-EPR capped with alkanethiolate monolayers exhibits high conductivity, low roughness, ultraflexibility, and strong corrosion resistance. Using the transferring process, AgNWs-EPR was successfully constructed on rough, adhesive, flimsy, or complex curved substrates, including PET, thin optically clear adhesive, papers, a beaker, convex spherical PDMS, and leaves. A flexible touch panel enabling multitouch and a curved transparent heater on a beaker were first fabricated by using the composite film. These demonstrations suggest that the proposed technique for AgNWs is a promising strategy toward the next generation of flexible/portable/wearable electronics.
我们提出了一种通用且实用的转移技术，可在任意衬底上制造具有高性能和极高稳定性的银纳米线（AgNW）透明电极。用 AgNW 修饰的羟基化聚对苯二甲酸乙二醇酯（PET）或聚二甲基硅氧烷（PDMS）可降低其极性表面能，从而可将 AgNW 轻松有效地转移到环氧树脂（EPR）中形成独立膜（AgNWs-EPR）或转移到各种衬底上。用烷硫醇单层覆盖的 AgNWs-EPR 具有高导电性、低粗糙度、超柔韧性和强耐腐蚀性。使用这种转移工艺，AgNWs-EPR 成功地构建在粗糙、粘性、脆弱或复杂弯曲的衬底上，包括 PET、薄光学透明胶、纸张、烧杯、凸面 PDMS 和叶片。首次使用复合膜制造了具有多点触控功能的柔性触摸板和烧杯上的弯曲透明加热器。这些演示表明，所提出的 AgNW 转移技术是下一代柔性/便携式/可穿戴电子产品的一种有前途的策略。
