Calcium carbonate (CaCO3) was mineralized in N,N-dimethylformamide (DMF)-H2O mixed solvents in the presence of polystyrene-b-poly (vinyl pyrrolidone) (PS-b-PNVP) block copolymer. The morphologies of PS-b-PNVP micelles and CaCO3crystals were characterized by TEM and SEM. By varying the volume ratio of DMF-H2O, the CaCO3crystals with different morphologies and phases were obtained. It was convinced that the morphology of crew cut micelles played a key role in the morphological formation of CaCO3.
