Flexible silver nanowires (AgNWs) transparent conductive films (TCFs) were fabricated on poly(ethylene terephthalate) (PET) substrate by using spray coating process. Effects of concentration and amount of AgNWs suspension on the performances of optoelectronics and microstructures of AgNWs TCFs were investigated. The experimental results demonstrate that as the increase of both of concentration and amount of AgNWs suspension, the sheet resistance and nonuniformity factor of the sheet resistance (NUF) and transmittance of AgNWs TCFs decrease and the root mean square (RMS) roughness and figure of merit (FoM) and haze of the AgNWs TCFs increase, respectively, due to the increase of the deposition density of AgNWs on the substrate. The flexible AgNWs TCFs with excellent comprehensive performance, which is a NUF of 0.48, haze of 1.94%, FoM of 148.5, transmittance of 84.5%, and sheet resistance of 12.95 Ω⋅sq−1, can be obtained under the proper experimental conditions. The pressure treatment can improve the electrical conductivity of AgNWs TCFs due to the increase of contact area and the decrease of contact resistance. AgNWs TCF with pressure treatment also exhibits excellent reliability against mechanical bending over 1000 cycles. Our works demonstrate that flexible AgNWs TCFs with high performance can be obtained by using spray coating method, which is one of the common techniques for preparing coatings or films.

使用喷涂制备高性能柔性透明导电银纳米线薄膜

采用喷涂工艺在聚对苯二甲酸乙二醇酯 (PET) 基板上制备柔性银纳米线 (AgNWs) 透明导电薄膜 (TCFs)。研究了AgNWs悬浮液的浓度和用量对AgNWs TCFs的光电性能和微观结构的影响。实验结果表明，随着AgNWs悬浮液浓度和用量的增加，AgNWs TCFs的薄层电阻（NUF）和透射率的薄层电阻和不均匀因子降低，均方根（RMS）粗糙度和品质因数降低。由于 AgNWs 在衬底上的沉积密度增加，AgNWs TCF 的 (FoM) 和雾度分别增加。柔性AgNWs TCFs具有优异的综合性能，其NUF为0.48，雾度为1.94%，FoM为148.5，12.95 Ω⋅平方-1, 可以在适当的实验条件下得到。由于接触面积的增加和接触电阻的降低，压力处理可以提高 AgNWs TCFs 的导电性。经过压力处理的 AgNWs TCF 在 1000 次以上的机械弯曲中也表现出出色的可靠性。我们的工作表明，使用喷涂方法可以获得高性能的柔性 AgNWs TCFs，这是制备涂层或薄膜的常用技术之一。
