Menetelmä mikro- tai nanorakenteiden valmistamiseksi polymeerikalvomateriaaliin |
摘要 |
The invention relates to a method for producing micro- or nanostructures in polymer film materials having thermoforming properties in an extrusion process. The method according to invention comprises providing a molten thermoforming polymer film (1) from an extruder (2), driving a molten polymer film (1) through a nip (3) wherein the molten thermoforming polymer film (1) is contacted with a cooling roller (4) supporting a master film with a surface relief pattern (5) and a pressure roller (6), so that micro- or nanostructures are replicated onto the polymer film by the action of pressure and cooling at the nip. The master film is a polymeric master film it is driven continuously from the master film feed roller (9) through the nip (3) to the receiver roller (10). |
