Investigating the effect of the micelle structures of block and random copolymers on dye solubilization.

To elucidate the correlation between dye solubilization into micelles and their core-shell aggregated structure, the structures of block and random copolymer micelles were characterized. The block copolymer micelles exhibited a higher dye solubilization capacity which correlated with their core volume, clear core-shell contrast and slow solubilization rate.
