In this paper, we used tannic acid (TA) functionalized carbon nanotubes (TCNTs), and silver nanowires (AgNWs) to construct a new type of transparent conductive film (TCF) with a double-layered conductive network structure. The hybrid film exhibits excellent light transmittance, high electrical conductivity, ultra-flexibility, and strong adhesion. These outstanding performances benefit from the filling and adhesion of hydrophilic TCNT layers to the AgNW networks. Besides, we introduced the post-treatment process of mechanical pressing and covering polymer conductive polymer PEDOT:PSS, which obtained three layers of TCNT/AgNW/PEDOT hybrid film and greatly improved the comprehensive properties. The hybrid film can reach a sheet resistance of 9.2 Ω/sq with a transmittance of 83.4% at 550 nm wavelength, and a low root mean square (RMS) roughness (approximately 3.8 nm). After 10000 bends and tape testing, the conductivity and transmittance of the hybrid film remain stable. The resistance of the film has no significant degradation after 14 days of exposure to high temperature of 85 °C and humidity of 85%, indicating excellent stability. The organic light-emitting diodes (OLEDs) with TCNT/AgNW/PEDOT hybrid film as anode exhibit high current density and luminosity, confirming this process has considerable potential application in photovoltaic devices.

用于有机发光二极管的高透明、低薄层电阻和稳定的单宁酸改性-SWCNT/AgNW 双层导电网络

在本文中，我们使用单宁酸（TA）功能化的碳纳米管（TCNTs）和银纳米线（AgNWs）构建了一种具有双层导电网络结构的新型透明导电膜（TCF）。该混合薄膜具有优异的透光率、高导电性、超柔韧性和强附着力。这些出色的性能得益于亲水性 TCNT 层对 AgNW 网络的填充和粘附。此外，我们还引入了机械压制和覆盖聚合物导电聚合物PEDOT:PSS的后处理工艺，得到了三层TCNT/AgNW/PEDOT杂化薄膜，综合性能大大提高。混合薄膜可以达到 9.2 Ω/sq 的薄层电阻，在 550 nm 波长下的透射率为 83.4%，和低均方根 (RMS) 粗糙度（约 3.8 nm）。经过10000次弯曲和胶带测试，混合膜的导电率和透光率保持稳定。薄膜在85℃高温、85%湿度下14天后电阻无明显下降，表明稳定性极佳。以 TCNT/AgNW/PEDOT 混合膜作为阳极的有机发光二极管 (OLED) 表现出高电流密度和发光度，证实该工艺在光伏器件中具有相当大的潜在应用。
