Abstract: Self-assembly of asymmetric coil-rod-coil three block copolymers is simulated with self-consistent field theory in three dimensions. As volume proportions of coil and rod block equal each other, with change of volume fractions of aside coil, lamellar, gyroid, strip and cylindrical structures are observed. Interacion parameter at which phase separation occurs increases with volume fractions of aside coil. As volume fraction of aside coil equals 0.05, phase behaves especially rich. With increasing interacion parameter self-assembly structure change from lamellar into gyroid and then lamellar, which is different from coil-rod diblock copolymers. It is found that appearance of lamellar, gyroid, strip and cylindrical structures differs with corresponding coil-rod-coil symmetric tfiblock copolymers.

Key words: self-consistent field, copolymers, self-assembly, phase separation
