Near-critical liquid/liquid interfaces of simple and complex mixtures probed by ellipsometry

Schulz, Jens; Hirtz, Andrea; Findenegg, Gerhard H. - In: Physica A: Statistical Mechanics and its Applications 244 (1997) 1, pp. 334-343

Measurements of the coefficient of ellipticity ϱ of light reflected at liquid/liquid interfaces of five binary mixtures are presented and analyzed in terms of theories which account for the interfacial thickness on the basis of the intrinsic profile and capillary waves. For simple mixtures of...

Critical adsorption at the surface of a polymer solution. Analysis of ellipsometric data on the depletion layer near the critical solution point

Süssmann, Rainer; Findenegg, Gerhard H. - In: Physica A: Statistical Mechanics and its Applications 156 (1989) 1, pp. 114-129

The structure of the liquid-gas interface of a polymer solution, polystyrene (MW=110.000) in cyclohexane, has been studied at temperatures and concentrations near the critical solution point (Tc=294.75 K, wc=10.2wt%) using ellipsometry. In the one-phase region of the liquid (T Tc) the...
