| Abstract: | The water-soluble amphiphilic derivatives of carboxymethylchitosan(CMCHS), (2-hydroxyl-3-(butoxyl)) propyl-carboxymethylchitosan(HBP-CMCHS) were prepared via the reaction of CMCHS with butyl glycidol ether. The structure of the resulting derivatives were identified by means of IR, NMR and X-ray (diffraction). The surface tension and surface (pressure) were measured. The results show that HBP-CMCHS can adsorb to the surface to decrease the surface tension of the solution, and the surface pressure of the adsorbed film increases dramatically with the (decrease) of the surface area. The surface activity increases with the (increase) of the degree of substitution(DS). For the derivative with DS=42.2%, the surface tension (decreased) to 32.5 mN/m, which (indicates) that the derivative can be used as a polymeric surfactant. |
