제목 Structure of Complex Coacervate Core Micelles
초록 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. In this study, we investigate the structure of complex coacervate driven micelles (C3M) as a function of charged block length, pH by dynamic light scattering (DLS) and small-angle X-ray/ Neutron scattering (SAXS/SANS). 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 relatively monodisperse C3Ms are formed by simple mixing, In particular, we observed scaling relationship between core dimension and charged block length, which is analogous to traditional block copolymer micelles. These results are discussed in terms of current understanding of complex coacervate and their self-assembly.
