1. A method for preparing a textured surface, comprisingtreating a surface of a shrinkable thermoplastic material with a plasma to increase stiffness of an outer layer of the surface relative to a subsurface layer;
- constraining opposite sides of the plasma-treated thermoplastic material;
thermally shrinking the constrained plasma-treated thermoplastic material under conditions to buckle the outer layer to form a layer with nanoscale wrinkles or textures having an average height from about 100 nm to about 5 micrometers above the subsurface layer of the material.
