The microphase separation of miktoarm block copolymers with different compositions and chain rigidities is studied using dissipative particle dynamics in two dimensions. The pure coil, rod-coil, and pure-rod models are considered, and complex micelles, tubular micelles, lamellae and networks morphologies are obtained for these systems. The influence of the molecule flexibility and shape on the morphology is emphasized for the special “Y”- and “T”-shaped miktoarm block copolymers. From an application point of view, these results will be helpful for designing new templates of block copolymers in thin films for the fabrication of nanostructures.
