摘要： A solid nano- or micro-structured thermoplastic foil including a nano- or micro-structured surface area is produced by providing an extrusion casting roller for an industrial polymer extrusion casting process using a thermoplastic material, applying a nano- or micro-structured surface on the extrusion casting roller, maintaining a temperature of the casting roller below a solidification temperature of the thermoplastic material while the casting roller and the counter roller are rotating, and continuously applying a melt of the thermoplastic material between a counter roller and the casting roller while the casting roller and the counter roller are rotating. A rotational velocity of the casting roller may be 10 meters/minute. The melt of the thermoplastic material is moved between the casting roller and the counter roller while the rollers are rolling, and the melt of the thermoplastic material is solidified upon contact with the casting roller to form the thermoplastic foil.

摘要： Aspects of the disclosure relate to methods for making large areas of high aspect ratio micro or nanostructured foil using existing extrusion coating equipment. A method is disclosed for producing a high aspect ratio micro- or nanostructured thermoplastic polymer foil, or a nanostructured thermoplastic polymer coating on a carrier foil, comprising at least one high aspect ratio nanostructured surface area. The method comprises applying a high aspect ratio nanostructured surface on an extrusion coating roller and maintaining the temperature of the roller below the solidification temperature of the thermoplastic material. A thermoplastic foil and a thermoplastic coating made by the method is also disclosed.

摘要： 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.
