Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.
