Abstract

A Ginzburg-Landau expansion of the free energy was used to study analytically the confinement effects of block copolymers between two surfaces as well as the interfacial behavior close to a single surface. For a BCP melt below its bulk ODT temperature, tilted lamellar phases were shown to exist between one patterned and one homogeneous surface of the chemical pattern is strong enough, and if no other defects exist inside the film.
