These factors mainly include the solution temperature , the type of selective solvents , the lengths of blocks , the crystalline block , the hydrogenbond interaction between the blocks and the solvent as well as the concentration of the block copolymers. The experimental methods for controlling the micelle morphology of amphiphilic block copolymers in selective solvents are then summarized . The recent advances in the micellar behaviors of a special
