摘要：

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 approximate to 0, It is clear that chitosan is a cationic macromolecular surfactant with special structure and properties.
