摘要

A cell dynamics simulation is performed for a diblock-diblock copolymers mixture confined between parallel walls. Much richer morphologies are observed in the mixture than in pure diblock copolymers. Multiple novel morphological transitions occur by changing the wall-block interaction and the distance between walls (confinement degree), and both perpendicular and parallel multilayered sandwich structures are obtained in the mixture.
