Abstract
The present disclosure discloses a functional fluid gating control system, which comprises a porous membrane and a functional fluid. The functional fluid at least partially infiltrates the porous membrane and cooperates to form a fluid gating pathway. The functional fluid and/or the porous membrane responds to at least one stimulus and undergoes a physical change or a chemical change to change the threshold pressure of the transport substance. A transport fluid being immiscible with the functional fluid is controlled to pass through the fluid gating system, and thus controllable transport and multiphase separation of materials are achieved. The stimulus of the present disclosure comprises a wide range of sources, and the stimulus responsiveness of the functional fluid and the porous membrane can be randomly and freely combined to adapt to multiple stimuli from complex external conditions and achieve intelligent controllability.
