Application of Polymer Adsorption Models to Dynamic Surface Tension

The Langmuir kinetics model and van Eijk and Cohen Stuart's spreading disk model were used to predict the dynamic surface tension of aqueous poly(N-isopropylacrylamide). Both published experimental results and calculations based on self-consistent field theory were used to convert the concentrations of adsorbed polymer to surface tension. The modeling could predict the slopes of surface tension versus log time curves; however, the times scales …
