Abstract :
The adsorption kinetics of surfactants onto the crystal surface spin-coated with a thin layer of a model membrane material, polyethersulfone was monitored through measurements of frequency and dissipation shifts simultaneously using a quartz crystal microbalance with dissipation (QCM-D) apparatus. In this study, the viscoelastic behaviors of the adsorbed surfactant layers of sodium laureth sulfate, cocamidopropyl betaine and their mixed solution (1:1) expressed through the dissipation parameters from the QCM-D measurements were used to deduce the structures of the adsorbed layers of the surfactants as a combinative result of characteristics of the surfactant and the hydrophobicity of the membrane surface.
