Complex coacervation is a liquid-liquid phase separation when two oppositely charged polyelectrolytes are mixed in an aqueous solution. Because of low interfacial tension and hydrophilicity, the complex coacervation process has been applied to various fields including pharmacy, cosmetics and food. In this study, we investigate the structure of complex coacervate driven micelles (C3M) as a function of charged block length, pH, and salt. 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 monodisperse C3M are formed by simple mixing, and core radii reduce as salt concentration increases. In particular, we observed scaling relationship between the core radius and core block length, which shows similarity to traditional block copolymer micelles. These results are discussed in terms of current understanding of complex coacervate and their self-assembly. |
