Structure and dynamics of water at liquid-vapour interfaces covered by surfactant monolayers of neutral stearic acid and charged stearate ions
چکیده انگلیسی
The behaviour of water molecules at liquid-vapour interfaces with a surfactant monolayer of either stearic acid molecules or anionic stearate ions is investigated by means of molecular dynamics simulations. The density and dipolar orientational profiles and also the dynamics of translational and rotational motion of interfacial water molecules are calculated in the present work and the results are compared with the bulk liquid water and also of liquid-vapour interface of surfactant-free water. The present simulation results are also compared with available experimental results of similar interfacial systems with a monolayer of either neutral or ionic surfactants.
