Abstract

In this paper, the thickness and stability of common black films (CBFs) in two ionic–nonionic mixed surfactant systems were compared based on the phase diagram of the adsorbed film. The mixed surfactant systems examined were (1) cetyltrimethylammonium chloride (CTAC) – n-dodecyl-β-D-maltoside (β-C12G2) and (2) lithium perfluorooctanesulfonate (LiFOS) – tetraethyleneglycolmonooctyl ether (C8E4) systems. When the attraction between the two surfactants in the adsorbed film was weak, the foam film collapsed as the observed bulk composition of the nonionic surfactant, X^2, became 0.09 in system (1). However, the CBF of system (2) was stable up to X^2 > 0.96 due to the strong synergism between the ionic and nonionic surfactants maintaining a high ionic surfactant composition in the adsorbed film, thus leading to a high surface charge density that stabilize the CBF.
