제목 Phase coherence upon heating in diblock copolymer films
초록 We have performed the mean field calculation on the thin films of diblock copolymers that microphase separate upon heating in the bulk. The thin films are confined between two different surfaces. The density profiles of block components were obtained through the film thickness as a function of temperature. The decay lengths of the observed surface ordering and phase coherence transitions upon heating were determined from the profiles. The recently developed compressible Landau analysis has been applied to the copolymer films to interpret the experimental reflectivity results. It was shown that specific interactions and finite compressibility are the two major issues concerning the observed behavior for the copolymers.
