▎ 摘　　要

Transparent conducting films composed of stacked layers (reduced graphene oxide (rGO)/silver nanowire (AgNW)/polymer) were prepared by low-cost wet processes. The arithmetic mean roughness value (R-a) of the rGO surface was about 3-4 nm. One of the films using poly (perfluoro-4-vinyloxy-1-butene) (Cytop)) showed a 4.0 Omega/sq sheet resistance and a 75% diffuse transmittance at 550 nm, values similar to those of commercial indium-tin-oxide (ITO) glass. The film possessed a much wider transparent wavelength region (65% at 300 nm and 80% at 2000 nm) than ITO. Scanning electron microscope (SEM) images of the films using poly(methyl methacrylate) (PMMA) indicated that the rGO top layer made all the surface conductive, and prohibited the corrosion of AgNW. The protective function was confirmed by sulfur vapor treatment and the mechanism was discussed. (C) 2013 Elsevier B.V. All rights reserved.
