旋涂法制备银纳米线透明导电薄膜

Siliver Nanowire Transparent Conductive Films Fabricated with Spin-coating Method

摘要:

以商用银纳米线分散液为原料,利用旋涂法在载玻片上制备透明导电薄膜,并测试其可见光波段透过率,分析银纳米线分散液浓度、旋涂转速和热处理对银纳米线透明导电薄膜性能的影响。实验结果表明,银纳米线分散液浓度为2 mg/mL,旋涂转速为7500 rpm时,制得的银纳米线透明导电薄膜透过率可达98 %,电阻为120 Ω；120 ℃热处理10 min后银纳米线透明导电薄膜的透过率降低至91%,电阻降低至70 Ω。通过旋涂法制备了具有较好光电性能的透明导电薄膜,有望应用于触控设备和有机发光二极管(OLED)等领域。

Abstract:

A transparent conductive film of silver nanowires was fabricated on glass substance via spin-coating method by commercial silver nanowires, and the transmission spectra andresistance of transparent conductive films were tested by UV-vis spectrophotometer and other technologies.. The effect of the concentration of silver nanowires, the speed of spin-coating and the heat treatment on photoelectrical properties was investigated. The results show that transparent conductive films with the transmittance of 98% are obtained when the concentration is 2 mg/mL and the speed of spin-coating is 7500 rpm; and drop to 91 % after heat treatment at 120 ℃. Transparent conductive films with high photoelectrical properties are fabricated via spin-coating process,which may be used in touch screens and Organic Light-Emitting Diode(OLED).
