Adsorption of Poly(acrylic acid) at an Oppositely Charged Langmuir Film:  Surface-Tension, Ellipsometry, and Elasticity Measurements

We have studied the adsorption of a weak polyelectrolyte at the free surface of water covered with an oppositely charged Langmuir film as a function of the surface density σ of the Langmuir film. The adsorption is slow (a few hours). The equilibrium surface pressure π of the mixed film and its compr...
