Abstract

Films of diblock copolymers with thicknesses less than a lamellar period on a noninteracting surface were found to be model systems for studying the late stages of two dimensional phase separation. It was found under conditions of constant surface coverage that the average particle size R(t), the inverse of the total number of particles N(t)-1, and the correlation length (t) varied as t, t2, and t, respectively, where =0.230.03.
