Abstract:
Methods for producing a high aspect ratio nanostructured thermoplastic polymer foil, or a nanostructured thermoplastic polymer coating on a carrier foil, including at least one high aspect ratio nanostructured surface area are described herein. A method may include providing an extrusion coating roller for an industrial polymer extrusion coating process using a thermoplastic material, applying a high aspect ratio nanostructured surface on the extrusion coating roller thereby forming a high aspect ratio nanostructured extrusion coating roller, maintaining the temperature of the high aspect ratio nanostructured extrusion coating roller below the solidification temperature of the thermoplastic material, moving a carrier foil between the rotating high aspect ratio nanostructured extrusion coating roller and a rotating counter pressure roller, and continuously applying a melt of the thermoplastic material between the moving carrier foil and the rotating high aspect ratio nanostructured extrusion roller.
