Abstract

Real‐space self‐consistent field theory (SCFT) is employed to study the effect of solvent molecular size on the self‐assembly of amphiphilic diblock copolymer in selective solvent. The phase diagrams in wide ranges of interaction parameters and solvent molecular size were obtained in present study. The results indicate that the solvent molecular size is a key factor that determines the self‐assembly of amphiphilic diblock copolymer. The self‐assembled morphology changes from circle‐like micelle to line‐like micelle, then to loop‐like micelle by decreasing the solvent molecular size in a wide range of solvent selectivity. We analyze and discuss this change in terms of the solvent solubility and the entropy contribution.
