Abstract
Stable black films are prepared for the first time from aqueous solutions of Tween 80-bovine serum albumin mixtures. Conditions for their formation and stabilization factors are studied in a Scheludko-Exerowa cell by microinterferometry. It is found that such films are formed when saturated surface layers consist of surfactant-protein 1: 1 complexes, Tween 80 molecules, or their mixtures. A possible mechanism for the thinning of liquid layers and the stabilization of black films is discussed.
