Optimal Processing for Hydrophobic Nanopillar Polymer Surfaces Using Nanoporous Alumina Template

Article Preview

Abstract:

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. A molded plastic thin film nanostructure is fabricated by nanoimprinting using the AAO template as a mold. The surface properties of the molded plastic thin film are discussed using various nanoimprinting process parameters. Contact angles of the molded plastic thin film with the nanostructure exceed those without the nanostructure. The molded plastic thin films with a nanostructure and a hydrophobic surface are formed, and their contact angles exceed 90°.
