Silver nanowires (AgNWs) show promise for fabricating flexible transparent conductors owing to their excellent conductivity, high transparency, and good mechanical properties. Here, we present the fabrication of transparent films composed of AgNWs with diameters of 20-30 nm and lengths of 25-30 μm on polyethylene terephthalate substrates and glass slides substrates using the Meyer rod method. We systematically investigated the films' optoelectronic and electrothermal properties. The morphology remained intact when heated at 25-150 °C and the AgNWs film showed high conductivity (17.6-14.3 Ω∙sq), excellent transmittance (93.9-91.8%) and low surface roughness values (11.2-14.7 nm). When used as a heater, the transparent AgNW conductive film showed rapid heating at low input voltages owing to a uniform heat distribution across the whole substrate surface. Additionally, the conductivity of the film decreased with increasing bending cycle numbers; however, the film still exhibited a good conductivity and heating performances after repeated bending.
由于具有优异的导电性、高透明度和良好的机械性能,银纳米线(AgNWs)在制造柔性透明导体方面展现出了潜力。在此,我们展示了使用迈耶棒法在聚对苯二甲酸乙二酯基板和载玻片基板上制备由直径为20 - 30纳米、长度为25 - 30微米的AgNWs组成的透明薄膜。我们系统地研究了这些薄膜的光电和电热性能。当在25 - 150°C下加热时,其形态保持完整,且AgNWs薄膜显示出高导电性(17.6 - 14.3Ω∙sq)、优异的透光率(93.9 - 91.8%)以及低表面粗糙度值(11.2 - 14.7纳米)。当用作加热器时,透明的AgNW导电薄膜由于在整个基板表面具有均匀的热分布,在低输入电压下显示出快速加热的特性。此外,薄膜的导电性随着弯曲循环次数的增加而降低;然而,在反复弯曲后,该薄膜仍表现出良好的导电性和加热性能。
