Abstract
The present invention is a method that (i) allows for creating micro and/or nanostructures on either planar or non-planar three-dimensional surfaces in a single molding step, and (ii) allows for the molded production of complex high-aspect ratio micro and/or nanostructures including but not limited to cylinders, conical structures, low aspect-ratio channels, bumps, or posts. An example of such a complex structure are high aspect ratio pillars with enlarged 'mushroom-shaped' or undercut tips which demonstrate enhanced, repeatable adhesion and shear strength on a variety of substrates when compared with other micro and/or nanostructures and unstructured materials. The mold of such a material requires an 'undercut' feature that cannot be produced using typical micro/nano-molding processing techniques.
