Surface Properties of Self-Organized Honeycomb-Patterned Films

Abstract

ABSTRACT This paper describes the preparation of honeycomb-patterned films from hydrophobic fluorinated copolymers. Micro-porous polymer films from fluorinated copolymers with hexagonally arranged micro-pores were prepared by casting polymer solution under humid condition. The pore size of the honeycomb-patterned film was controlled by changing casting volume. The water contact angles on the honeycomb-patterned films were measured with changing their pore sizes. The water contact angle increased up to 145°, when the pore size decreased. These values fitted the theoretical calculations.
