TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The method (M2) involves: heating each of several polymers respective (Tg); continuously depositing (preferably by flowing or laying), a first of the polymers onto a molding surface (lower molding surface) of a first mold (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the polymer so deposited), where the first polymer remain above the (Tg); continuously depositing (preferably by flowing or laying), a second of the polymers onto the exposed surface of the first polymer (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the polymer so deposited) where the second polymer remains above the (Tg); continuously depositing (preferably by flowing or laying) at least one further polymer onto exposed surface of each further respective polymer, (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the polymer so deposited), where each of the further polymers remains above their respective (Tg); applying an molding surface (upper molding surface) of a second mold to at least the upper surface of the upper-most polymer while each of the polymers remain at a temperature above their respective (Tg), and allowing the polymers to transition to below their respective (Tg) while held within or between the molding surfaces, where after the polymers so formed are removed from the molding surfaces. The method (M3) involves: continuously advancing a polymer that is above its (Tg) into and through a forming zone where the polymer is subjected to, a pressure, and mold forming to impart a nano-scale sized surface texture (preferably nano-scale sized texture has at least one dimension of 0.1-1000 nm) on to at least part of a surface of the polymer, and active heat removal to transition the polymer to below the (Tg), where after the forming zone the polymer is removed from the molding surfaces. The method (M4) involves: depositing a sheet of a polymer that is below its (Tg) onto a molding surface (lower molding surface) of a first mold (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the sheet so deposited); transitioning the polymer to above its (Tg); advancing the polymer into a pressure zone while supported by and with the lower molding surface and while remaining above its (Tg), where the pressure zone defined by the lower molding surface and a molding surface (upper molding surface) of a second mold positioned relative the upper molding surface to contact at least the exposed surface (upper surface) of the polymer while the polymer remains at a temperature above the (Tg) and to apply pressure to the polymer between the upper and lower molding surfaces and controlling the removal of heat from the polymer while in the pressure zone to transition the polymer to below the (Tg), where after the polymer is removed from the molding surfaces. Formation of two polymers involves: heating each of first polymer and a second polymer to temperatures above each polymer's respective (Tg); continuously depositing (preferably by flowing or laying) the first of the polymers onto a molding surface (lower molding surface) of a first mold, (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the polymer so deposited), where the first polymer remains above its (Tg), continuously depositing (preferably by flowing or laying) the second of the polymers onto the exposed surface (upper surface) of the first polymer, (preferably in a manner that reduces, eliminates or minimizes shear stress or other stress in the polymer so deposited), where the second polymer remains above its (Tg); applying a molding surface (upper molding surface) of a second mold to at least the upper surface of the second polymer while each of the polymers remain at a temperature above their respective (Tg), and allowing the polymers to transition to below their respective (Tg) while held within or between the molding surfaces, where after the polymers, bonded together, are removed from the upper and lower molding surfaces. The forming zone is defined by a serially advancing molding surface or surfaces (lower molding surface) of a first mold or molds and molding surface or surfaces (upper molding surface) of a second mold or molds. The whole of the polymers to be formed remain above their respective (Tg) during at least the initial applying of a forming pressure onto the polymer(s) between the upper and lower molding surfaces. The applying the upper molding surface involves: bringing the upper molding surface into contact with at least the upper-most surface of the upper polymer. The polymer(s) assume the shape of the lower mold surface and upper mold surface when above its polymers (Tg). The polymers is/are heated to above the (Tg) and is/are fed via extrusion to an extrusion head for flowing directly onto the lower molding surface. In the method, a melt pump controls the flow rate of polymer. The polymers when above the (Tg) is/are in the liquid phase. The molding surfaces are at temperature just above the (Tg) of die polymer(s) to be formed when the polymers are initially located between the upper and lower molding surface. The molding surfaces are maintained at temperatures above the (Tg) of the polymer(s) during the step of applying an upper molding surface to at 1easr the upper surface of the polymer or upper-most polymer. The applying the upper molding surface involves applies pressure to the polymer(s) for moving the polymer(s) into the molding surface(s)'s surface reliefs. The upper surface is applied to the polymer(s) to apply pressure to the polymer(s) by virtue of movement of the polymer between the two molding surfaces. The lower or upper molding surface is supported by a conveyor. The lower molding surface is supported and moved first conveyor and the upper molding surface is supported and moved by a second conveyor that is located adjacent the first conveyor to position the second molding surface adjacent the first molding surface and move the first and second molding surfaces through a pressure zone at where the polymer is subjected to pressure between the first and second molding surfaces. The polymer is above its (Tg) upon entering the pressure zone. The temperature is at least one of the first and the second molding surface is actively controlled in the pressure zone. The temperature of the lower molding surface is actively controlled prior to the pressure zone. The temperature of the lower molding surface is sufficiently high to help keep the polymer deposited on it, and prior to the polymer entering the pressure zone, above its (Tg). The actively controlled heat removal occurs from the polymer via at least one of the upper and lower molding surfaces, when the polymer is in the pressure zone, to transition the polymer from above its (Tg) to below its glass transition temperature within the pressure zone, at least by the virtue of the control of temperature of at least one of the first and second molding surfaces. The method is used to form nano-scale sized texture (preferably the nano-scale texture has at least one dimension of 0.1-1000 nm) onto at least one of the surfaces of the polymer.Preferred Components: The molding surfaces comprise surface reliefs.
