摘要：

A strategy toward tuning amphiphilic block copolymer micellar morphology is proposed in this study. A binary solvent mixture of water and acetone with different acetone content instead of a unitary solvent of water is used as block-selective solvent to associate polystyrene-b-poly(acrylic acid-co-methyl acrylate) and polystyrene-b-poly(acrylic acid) chains into various morphological micelles. Following this method by adjusting the acetone content in the binary solvent mixture, various morphological micelle-like aggregates such as core-shell spheres, porous aggregates, core-shell cauliflower-like aggregates, and nanofibers are formed. The various morphological aggregates are observed by TEM and characterized by light scattering, and the possible reason for micellar morphology tuning is discussed.
