Abstract
Disclosed herein is a method comprising deforming an organic polymer composition at a temperature below a glass transition temperature of an organic polymer in the organic polymer composition; the deforming being conducted by an application of a shear force, an elongational force, a compressive force, or a combination comprising at least one of the foregoing forces; the forces being applied to the organic polymer composition as it is disposed between a first roll that comprises a rubber surface and a second roll that comprises a textured metal surface; the deforming producing a textured film having a ratio of texturing of about 0.5 to about 3; the textured film having a thickness of about 5 to about 75 micrometers and an average roughness of about 0.3 to about 6 micrometers on opposing surfaces of the film.
