The self-assembly of miktoarm star-like block copolymers in dilute solution was studied with dissipative particle dynamics(DPD) simulations. The pathway of self-assembly, as well as the influence of molecular architecture of the block copolymers on the self-assembly structures were studied in this paper. The miktoarm star-like block copolymers aggregate into disk-like micelles, then the micelles can close to form a vesicle. For the system with short hydrophilic branch, it is easy to form the vesicle, and the thickness of the bilayer membrane of vesicle is larger since the hydrophobic branches of the miktoarm star-like block copolymers are longer. The results show that it is easier for the miktoarm star-like block copolymers to assemble into vesicles than for the corresponding linear diblock copolymers.
