Aqueous foams are a typical type of soft matter that are widely used in detergents, cosmetics, food engineering, and oil and gas production because of their relatively small particle size, large superficial area and good fluidity. The stability of a foam plays a crucial role in determining its performance in practical applications. Smart foams, with controllable stability, have been developed recently and their stability can be regulated by external stimuli. This review article mainly focuses on the recent progress in intelligent aqueous foams. To date, smart aqueous foams with temperature, light, magnetic field, pH and CO2-responsive behaviors have been obtained by introducing sensitive groups into foaming agent molecules or adding stimuli-responsive particles to foaming systems. The formation mechanism and properties of different types of smart aqueous foams are summarized and discussed. The potential applications and future prospects of smart foams are also considered.

Key words: Smart foam, Foamability, Stability, Stimuli-responsive
