Abstract

Controllable helical domain structures and some related exotic domain structures can be realized in simple diblock copolymer systems under an external field. These domain structures are obtained in self consistent field (SCF) simulations and experiments. A phase diagram constructed by SCF simulations predicts a series of morphological transitions between different domain structures by controlling the strength of the external field.
