Research on Rheological Behavior of Anion Gemini Surfactant Solution

Abstract:

The effects of the hydrocarbon chains and spacer groups of a series of sulfate anion Gemini surfactants(Cm-s-m.2Na+) on the rheological behavior are investigated in this paper. Results show that either length of carbon chain increases or length of linking group decreases, solution viscosity increases, C12-2-12.2Na+ has the best viscosifying ability. Then variation of viscosity of C12-2-12.2Na+ solution with concentration, pH, shear rate, temperature, and hydrolyzed polyacrylamide (HPAM) are observed. Results indicate that viscosity increases as concentration increases; single-chain cationic surfactants make viscosity increases first then decreases; concentration of multivalent ion increases or temperature raises or shear rate increases, corresponding viscosity decreases; while pH increases, corresponding viscosity rises first and decreases later; HPAM can enhance the viscosity of C12-2-12. 2Na+ solution, showing that gemini surfactant has a good synergism with HPAM.
