Abstract

Abstract:

Surfactants play an important role in microfluidic applications, often accompanied by dynamic interfacial tension. The research progress of multiphase flow containing surfactants in microchannels is reviewed, and the relationship between droplet size, liquid rheology, pressure drop and dynamic interfacial tension in microfluidics is analyzed. The interfacial transport phenomena under the action of surfactants, such as the formation, movement, deformation, breakup and coalescence of bubbles and droplets are summarized. The adsorption kinetics of surfactants in microfluidics are reviewed, and research directions in this field for the future are prospected.

Key words: surfactant, microfluidics, interfacial dynamics, transport phenomena, multiphase flow
