Surfactants are widely used in many industries because of their excellent surface activity.In recent years,controllable intelligent surfactant systems which can transition between stable and non-stable states have attracted great attention.In view of the research progress on intelligent surfactants in recent years,paper the intelligent systems such as emulsions,stimulus-responsive surfactants and corresponding intelligent dispersion systems were reviewed,the formation mechanism and corresponding properties of different types of intelligent emulsions were discussed,and the application prospect and development direction of intelligent surfactants was prospected.
