Abstract

A highly uniform and hydrophobic nanopillar film was fabricated by nanoimprinting using the AAO template as a mold in this study. Nanoporous anodic aluminum oxide (AAO) templates are fabricated using an anodization method. The mean diameters of nanoporous anodic aluminum oxide templates are 100 nm and 200 nm by various processing parameters of the anodization method. The surface properties of the molded plastic thin film are discussed using various nanoimprinting process parameters. The results reveal that the contact angles of the molded plastic thin film with the nanopillar exceed those without the nanopillar. The molded plastic thin films with a nanopillar and a hydrophobic surface are formed, and their contact angles exceed 120°. The results also appear that the hydrophilic property of molded plastic thin film without nanopillar changes to hydrophobic property of molded plastic thin film with nanopillar.
