Nature of Amine-Surfactant Interactions at the Air-Solution Interface (dagger).

Abstract:

The surface tension and adsorption behavior of polymer/surfactant mixtures of polyethyleneimine (PEI)/sodium dodecyl sulfate (SDS) is strongly dependent on pH. At both low and high pH, a strong PEI/SDS interaction gives rise to surface polymer/surfactant complex formation that results in significantly enhanced SDS adsorption at very low SDS concentrations and in multilayer formation at the interface. At low pH, this strong PEI/SDS interaction is dominated by the electrostatic attraction betwe...
