High-Performance Silver Nanowire Film on Flexible Substrate Prepared by Meyer-rod Coating

摘要

Flexible and transparent conducting (FTC) films based on silver nanowires (AgNWs) were fabricated onto a polycarbonate (PC) substrate by a simple Meyer-rod coating process. AgNWs were synthesized using polyvinyl alcohol by polyol process with a diameter and length of 500 nm and 10 μm, respectively. The FTC film was fabricated by varying the number of layers. The FTC film exhibited a sheet resistance of 12.1 Ω.sq~(-1) with a transparency of 89.5%. The optical conductivity of FTC films was obtained about 4.7 - 13.1 × 10~5 S.m~(-1) with a refractive index about 1.2 to 1.7. The number of layers is an important to influence on the sheet resistance and transmittance of the FTC films. The sheet resistance and transmittance decreases with the number of layers.
