Abstract
ABSTRACTThe N-dodecyl chitosan sulfate (NDCS) with a higher degree of substitution of dodecyl was synthesized. The surface tension and transmission electron microscopy showed that the product had a higher surface activity and could self-assemble into bigger spherical polymeric micelles. Besides, the characteristics of complexation of NDCS with cetyltrimetylammonium bromide (CTAB) were studied by static/dynamic surface tension, turbidity and transmission electron microscopy. The results revealed that the mixture of NDCS with CTAB had a higher surface activity, lower diffusing rate and higher turbidity. Furthermore, they also could self-assemble into agglomerate or dispersed spherical aggregates in some concentration domain of CTAB.
