Superwetting interface for miscible liquid separation

Design of superwetting interface can regulate mass transfer in membrane separation. In a recent work published in Matter by Lei Jiang and colleagues, superwetting interface of polar (or nonpolar) porous membrane and low (or high) polar inductive agent enabled polar (or nonpolar) target liquid components to rapidly permeate the membrane but blocked other relatively nonpolar (or polar) liquid components, realizing miscible liquid separation driven by polar/nonpolar interactions.
