Abstract:

Oil-water interfacial viscosity for aqueous mixture of cetyltrimethylammonium bromide(CTAB ) and partially hydrolyzed polyarcylamide (HPAM) was studied. The results showed that interfacial viscosity dependends on the shearing rate and the hydrolysis degree of HPAM, the interfacial viscosity decreases with surfactant concentration A higher interfacial viscosity favors to enhance the emulsification stability of the aqueous mixture of HPAM and CTAB. Based on the experimental results, an explanation for CTAB-HPAM interaction at oil-water interface has been proposed.
