Recently, silver nanowires (AgNWs) have attracted considerable interest for their potential application in flexible transparent conductive films (TCFs). One challenge for the commercialization of AgNW-based TCFs is the low conductivity and stability caused by the weak adhesion forces between the AgNWs and the substrate. Here, we report a highly bendable, conductive, and transparent AgNW film, which consists of an underlying poly(diallyldimethyl-ammonium chloride) (PDDA) and AgNW composite bottom layer and a top layer-by-layer (LbL) assembled graphene oxide (GO) and PDDA overcoating layer (OCL). We demonstrated that PDDA could increase the adhesion between the AgNW and the substrate to form a uniform AgNW network and could also serve to improve the stability of the GO OCL. Hence, a highly bendable, conductive, and transparent AgNW-PDDA-GO composite TCF on a poly(ethylene terephthalate) (PET) substrate with Rs ≈ 10 Ω/sq and T ≈ 91% could be made by an all-solution processable method at room temperature. In addition, our AgNW-PDDA-GO composite TCF is stable without degradation after exposure to H2S gas or sonication.
最近，银纳米线（AgNWs）因其在柔性透明导电薄膜（TCFs）中的潜在应用而引起了相当大的关注。AgNW 基 TCF 商业化面临的一个挑战是 AgNW 与基底之间较弱的粘附力导致的低导电性和稳定性。在这里，我们报告了一种高度可弯曲、导电和透明的 AgNW 薄膜，它由底层的聚二烯丙基二甲基氯化铵（PDDA）和 AgNW 复合底层以及顶部的层层（LbL）组装氧化石墨烯（GO）和 PDDA 覆盖层（OCL）组成。我们证明 PDDA 可以增加 AgNW 与基底之间的粘附力，形成均匀的 AgNW 网络，还可以提高 GO OCL 的稳定性。因此，可以通过室温下的全溶液处理方法在聚对苯二甲酸乙二醇酯（PET）基底上制造出具有约 10 Ω/sq 的 Rs 和约 91%的 T 的高度可弯曲、导电和透明的 AgNW-PDDA-GO 复合 TCF。此外，我们的 AgNW-PDDA-GO 复合 TCF 在暴露于 H2S 气体或超声处理后没有降解，稳定性良好。
