Complex coacervation is a liquid-liquid phase separation when two oppositely charged polyelectrolytes are mixed in aqueous solution. Because of low interfacial tension and hydrophilicity, complex coacervate has been applied to the field of pharmacy and food industry. Especially, complex coacervate has stimuli-responsive property due to electrostatic interaction. In this study, we investigate the structure of complex coacervate driven micelles (C3M) as a function of charged block length, functional group and salt concentration by dynamic light scattering (DLS) and small-angle X-ray scattering (SAXS). C3M are formed by simple mixing of AB and A’B block copolyelectrolyte solutions in aqueous solution where A and A’ are oppositely charged blocks, and B is PEO. The results reveal that the core radii of C3Ms decreases with increasing salt concentration. In particular, we observed the difference of critical salt concentration (CSC) between core having different functional groups. |
