Abstract: A device for continuous seawater desalination of and a method thereof. A hydrophobic carbon nanotube composite membrane is made of a hydrophobic polymer and carbon-based materials, and the carbon-based materials are, such as, carbon nanotubes or graphene. The hydrophobic carbon nanotube composite membrane is perforated to obtain the hydrophobic carbon nanotube composite membrane having micrometer-nanometer multi-level pore structure using laser light. Further, a surface is coated with a photothermal-electrothermal responsive polymer to increase electric joule heat and photothermal effects to increase energy utilization efficiencies, and the hydrophobic carbon nanotube composite membrane having multi-level pore structure and electrothermal effects and photothermal effects is finally obtained. A device is designed, a hydrophobic carbon nanotube composite porous membrane is applied to electro-induced and light-induced seawater desalination, and conditions are controlled to enable the hydrophobic carbon nanotube composite porous membrane to generate heat.

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.
