在这里，我们报道了一种双层结构的透明、柔性混合电极，这种电极是由银纳米线（Ag NWs）的过渗网络和CVD石墨烯涂层在PET衬底上制成的。所制备的石墨烯/Ag NW杂化膜的电阻为T = 81.5% (550 nm), Rs = 32.5 Ω sq−1，与ITO的电阻相当。与Ag - NW薄膜相比，混合膜具有较低的表面粗糙度和较高的直流光导比。在这种电极结构中，石墨烯和Ag NWs可以分别作为短程导体和远程导体，它们可以更有效地收集和传输载流子到外部电路。此外，石墨烯/银NW薄膜具有理想的力学性能。石墨烯/银纳米复合电极有望成为一种柔性透明电极。
Herein we report a double layer structured transparent, flexible hybrid electrode from a subpercolating network of silver nanowires (Ag NWs) with CVD graphene coating on a PET substrate. The resistance of the obtained hybrid graphene/Ag NW film, with T = 81.5% (at 550 nm) and Rs = 32.5 Ω sq−1, is comparable to that of the resistance of ITO. In comparison with the Ag NW film, the resulting hybrid film has a lower surface roughness and a high DC to optical conductivity ratios. In such an electrode structure, graphene and Ag NWs can serve as the short-range and long-range conductors respectively, which should be more efficient in collecting and transporting the carriers to the external circuits. In addition, the graphene/Ag NW film possesses a desirable mechanical property. It is expected that the graphene/Ag NW double layered electrode might serve as a flexible transparent electrode.
