银纳米线/聚乙烯醇复合纳米薄膜的制备与性能研究

摘要

In this article, silver nanowires (AgNWs)/polyvinyl alcohol (PVA) composite nano-film was prepared by one step spin-coating. The content of the AgNWs in the film was controlled by the standing time of the droplets on substrates prior to spin. The sheet resistance and transmittance decreased with increasing of standing time,and simply related with the density of AgNWs in nano-film. We suggest that by properly controlling the standing time, we can directly prepare nano-films of high conductivity and transmission within a single processing.%本文采用旋涂法一步制备了银纳米线/聚乙烯醇(PVA)导电复合纳米薄膜,并通过控制液滴在基底表面的静置时间来控制银纳米线在薄膜中的含量,发现不同浓度分散液制备的纳米薄膜的层电阻和透过率会随着静置时间的增加而下降,且主要依赖于银纳米线的密度.本研究说明,通过控制合理的静置时间可以一步制得具有较高导电和透过性能的纳米薄膜.
