Abstract: An apparatus and method for forming a textured polymeric film are disclosed. The apparatus includes a first roller and a second roller, wherein the first roller and the second roller may be configured to cooperatively form the textured polymeric film. In one embodiment, a limited portion of at least the first roller is heated, passively, actively, or by a combination of active and passive techniques.

Abstract: A method for forming highly defined and detailed micro-channeled components using injection molding of polymeric material is presented. Such micro-channel components can be created by holding the temperature of the injection cavity and mold in excess of the glass transition temperature of the polymeric material while the polymer is injected. The polymeric material can also be injected under pressure to facilitate the forming of the highly defined micro-features. The newly created polymeric substrate can then be ejected form the mold and used in micro-fluidic and other applications requiring precise and uniform micro-channeled structures.
