Non-lithographic approach to the fabrication of polymeric nanostructures with a close-packed 2D hexagonal array

Abstract

A simple and completely non-lithographic route to free-standing nanostructured polymeric films with a close-packed hexagonal array of nanoembossments or nanorods is presented in which electrochemically prepared textured aluminum sheets or nanoporous anodic alumimum oxide are used. The Figure Shows an polystyrene/PMMA nanoparticle composite.
