Highly flexible silver nanowire-based transparent conductive films (AgNWs TCFs) were large-scale fabricated by slot-die coating AgNWs inks on a flexible polyethylene terephthalate (PET) substrate, and further fabricated into a transparent film heater. Appropriate flow rate, coating speed, and AgNWs concentration allow the construction of the 15 cm × 15 cm AgNW TCFs with a sheet resistance () of less than 20 Ω/sq, a transmittance () at 550 nm higher than 95%, and a haze less than 3.5%. The resultant AgNW TCFs heater possesses high uniformity and superior mechanical stability and can reach a Joule heating temperature of 104 °C with a voltage of 12 V. The slot-die coating method has great potential for large-scale production of AgNW based film heaters promisingly used in window defrost and deicer systems.
通过狭缝模头涂布法将银纳米线（AgNWs）墨水涂覆在柔性聚对苯二甲酸乙二酯（PET）基板上，大规模制备了高柔韧性的基于银纳米线的透明导电薄膜（AgNWs TCFs），并进一步制成透明薄膜加热器。合适的流速、涂布速度和AgNWs浓度能够制备出尺寸为15 cm×15 cm的AgNW TCFs，其方阻（）小于20 Ω/sq，在550 nm处的透过率（）高于95%，雾度小于3.5%。所得的AgNW TCFs加热器具有高度均匀性和优异的机械稳定性，在12 V电压下能达到104 °C的焦耳加热温度。狭缝模头涂布法在大规模生产基于AgNW的薄膜加热器方面具有巨大潜力，有望应用于车窗除霜和除冰系统。
