摘要：
Three dimensional real-space self-consistent field theory is employed to study the effect of conformational asymmetry on the self-assembly of amphiphilic diblock copolymer in selective solvent. The phase diagrams in wide ranges of interaction parameters and conformational asymmetry were obtained in present study. The results indicate that the conformational asymmetry is an important factor that determines the self-assembly of amphiphilic diblock copolymer in solution. The self-assembled morphology changes from sphere to rod, then to vesicle with an increase of the degree of conformational asymmetry. We found that the entropic contribution of the core-forming block is the main reason for this transition.
