We have successfully measured electron transport nanostructures of conjugated polymer thin films by conductive atomic force microscopy, using an air-stable electron-injecting electrode coated with ethoxylated polyethylenimine. Electron- and hole-transport networks in donor/acceptor polymer blends can be selectively observed by using an appropriately coated electrode. This approach enables us to visualize phase-separated nanostructures of donor/acceptor polymer blends for thin-film electronic devices based on their semiconducting properties.
我们通过导电原子力显微镜，使用涂有乙氧基化聚乙烯亚胺的空气稳定电子注入电极，成功测量了共轭聚合物薄膜的电子传输纳米结构。通过使用适当涂覆的电极，可以选择性地观察供体/受体聚合物共混物中的电子和空穴传输网络。这种方法使我们能够基于其半导体特性，可视化用于薄膜电子器件的供体/受体聚合物共混物的相分离纳米结构。
