Abstract: It is well known that block copolymers in selective solvents can self-assemble into
various micellar structures. Block copolymer self-assembly has attracted considerable attention for
many decades because these aggregates provide potential applications in many fields, such as
biomedical and nanomaterials. This review introduces the micellization of block copolymer in
block selective solvent and some important factors including the position, nature of
mon solvent, copolymer concentration and the presence of additives that influence the
morphologies are illustrated. At last, perspectives on potential applications of these aggregates are
discussed.
