文摘Measurements of surface tension,conductivity,aggregation behavior and solubilization of pyrene of chitosan aqueous solutions have been carried out.The results show that chitosan is surface-active,and can aggregate in single molecule,or critical aggregation number cac≈ 0.It is clear that chitosan is a cationic macromolecular surfactant with special structure and properties.
