摘要

For the first time, theological and dynamical properties of various interfacial layers separating an aqueous phase and a carbon dioxide phase under supercritical conditions have been measured by means of a drop tensiometer, applying either Sinusoidal or ramp interfacial area perturbation. Those approaches have been largely developed on liquid-air and liquid-liquid interface but very few studies were performed in pressurized conditions [F. Tewes, F. Boury, Formation and rheological properties of the supercritical CO2-water pure interface, J. Phys. Chem. B 109 (2005) 3990-3997; F. Tewes, F. Boury, Effect of H2O-CO2 organization on ovalbumin adsorption at the supercritical CO2-water interface, J. Phys. Chem. B 109 (2005) 1874-1881].
