Abstract: 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.

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.

Abstract: A method produces a smooth surface on a rough substrate. The rough substrate is coated with a film or particles of spin-on-glass (SOG) dissolved in a solvent using spin coating, spray coating or dip coating. The SOG is made to reflow by using thermal melting and solvent thinning. The reflow is done in an atmosphere containing a partial pressure of the solvent. The reflow allows the SOG to partially melt and to decrease the surface roughnesss of the film. The SOG is cured by thermal curing or UV exposure radiation curing into a hard durable and chemical inert silicon dioxide film. The SOG can be hydrogen silsesquioxane or methyl silsesquioxane dissolved in either methyl isobutyl ketone or volatile methyl siloxanes. The method can include embossing, chemical mechanical polishing, etching and functionalizing the surface. The substrate can be a cast, mould or form for producing a polymer or a glass replica.

Abstract translation: 一种方法在粗糙的基底上产生光滑的表面。 粗糙基材用旋涂，喷涂或浸涂法溶解在溶剂中的旋涂玻璃（SOG）的薄膜或颗粒涂覆。 SOG通过使用热熔融和溶剂稀释来回流。 回流在含有溶剂分压的气氛中进行。 回流焊使SOG部分熔融并降低膜的表面粗糙度。 SOG通过热固化或UV曝光固化成硬的耐久和化学惰性二氧化硅膜来固化。 SOG可以是溶解在甲基异丁基酮或挥发性甲基硅氧烷中的氢倍半硅氧烷或甲基倍半硅氧烷。 该方法可以包括压花，化学机械抛光，蚀刻和使表面官能化。 基底可以是用于生产聚合物或玻璃复制品的铸造，模具或形式。

Abstract: A method for producing a part by molding with an embedded 2D barcode defined in the surface of the part and the embedded 2D barcode subsequently being readable using a light source and a camera, the method including providing a mold with an array of individual areas of optical anisotropic surface structures, where at least a number of the individual optical anisotropic structures forms a two-dimensional barcode or data matrix; making a replica of the mold, the replica including the array having the property that the directional reflection coefficient of the individual areas of optical anisotropic surface structures is depending on the illumination angle and detection angle in a way that is not rotational symmetric around the axis normal to the surface of the replica, the array being readable by illumination and detection of reflection intensity of the illumination source under a non-normal angle to the surface of the replica.
