Abstract

Mixed films formed by an insoluble polymer, poly(dimethylsiloxane) (PDMS), placed on the surface of aqueous solutions of two different soluble surfactants are studied by a variety of different methods: surface tension isotherms, ellipsometry complemented by the neutron reflectivity experiments presented in part 2, and direct observations of the surface via the Brewster angle microscope. A vertical separation into superimposing surfactant and polymer layers is exhibited, with mixing between the layers depending on the surfactant. On one but not the other of the surfactant solutions studied, a lateral separation of the polymer monolayer is also observed, into domains similar to those previously observed on pure water. The collapse of the monolayer into a three-dimensional state with increasing polymer concentration occurs more smoothly than on water.
