摘要
比较了喷墨印刷和旋涂PEDOT∶PSS薄膜的表面性能, 发现喷涂PEDOT∶PSS薄膜上印有发射层油墨后, 其表面性能有很大差异。在喷墨打印PEDOT∶PSS膜的表面上只发现了大量的和类山状的聚合物颗粒。 进一步的研究表明, 形态的差异源于润湿性的不同。揭示了喷墨打印和旋涂对膜性能的不同影响, 从而在喷墨打印PEDOT∶PSS膜上构建了更精细的结构。
Abstract
A comparison between the surface properties of inkjet printed and spin coated PEDOT∶PSS films was made in consequence of the intriguing distinction after printing emitting layer inks on them. The sizable and hill-like polymer grains were only found on the surface of the inkjet printed PEDOT∶PSS film. Further investigation demonstrated the difference in morphology stems from the diverse of wetting properties. The differing effects on film properties between inkjet printing and spin coating were revealed, according to which a finer structure was constructed on inkjet printed PEDOT∶PSS film.
