Abstract

Surface structures of films cast from pyridine solutions of polystyrene (PS), poly(2-hydroxyethyl methacrylate) (PHEMA), and their mixture (PS/PHEMA=1/1, w/w) in air and water were examined with atomic force microscopy (AFM) using force volume mode. The AFM measurement was a useful tool to clarify that the PS/PHEMA blend film in water had a heterogeneous surface consisting of a hard PS matrix and soft PHEMA domains.
