In this article, a low sheet resistance and highly transparent silver nanowire (AgNW) resin composite film was demonstrated, which was prepared by a simple and efficacious two-step spin-coating method. By burying the AgNWs below the surface of the transparent resin matrix which was cured at 150 °C in air, we achieved a uniform, highly transparent, conductive, flexible film. Compared to the reported transparent electrodes, this composite transparent and conductive film showed 10 Ω/□ sheet resistance and nearly 90% mean optical transmittance over the UV-visible range simultaneously. Undergoing hundreds of cycles of tensile and compression folding, the composite film slightly increased its sheet resistance by less than 5%, displaying good electromechanical flexibility. These characteristics of the composite AgNW-resin films were expected to be used in applications of flexible optoelectronics.
在本文中，展示了一种低表面电阻且高透明的银纳米线（AgNW）树脂复合薄膜，其通过简单有效的两步旋涂法制备。通过将AgNWs埋入在空气中150°C固化的透明树脂基体表面以下，我们获得了一种均匀、高透明、导电且柔性的薄膜。与已报道的透明电极相比，这种复合透明导电薄膜在紫外-可见光范围内同时显示出10Ω/□的表面电阻和近90%的平均光学透过率。经过数百次拉伸和压缩折叠循环后，复合薄膜的表面电阻略有增加，增幅小于5%，显示出良好的机电柔韧性。AgNW-树脂复合薄膜的这些特性有望用于柔性光电子学应用中。
