Dewetting of polymer blends and formation of phase-separated polymer domes

Abstract

Phase-separated polymer droplets with micron-size diameter and nanometer-size height were prepared by casting a dilute solution of two polymers, polystyrene and poly(methylmethacrylate). Staining with an electron acceptor allowed us to distinguish between the two polymers by fluorescence microscopy. © 2006 The Surface Science Society of Japan.
