Micellar Conformation of Carboxy Methyl Cellulose Based Polymeric Surfactants in Aqueous Solution
The micellar conformation of polymeric surfactants based on carboxy methyl cellulose in aqueous solution was studied by dynamic laser scattering and environmental scanning electron microscope. The results show that different polymeric surfactants have different micellar conformation. The micelles formed by copolymer A3, B7 and B9 are spheroidal or ellipsoidal. While copolymer A9 which is more hydrophilic forms rod like micelles. At high concentration the micelles in aqueous solution would aggregate and form network structure further. The dependence of micelle size distribution function F(R) on scattering vector confirms again that the micelles of A9 is not like spherical, while the independence of F(R) on scattering angles means B9 molecules forming sphere like micelles.
