Bio-inspired fabrication of asymmetric wettability Janus porous membrane for secure F-oil infused F-free-membrane filtration

Bioinspired by the natatores's feather and mussels' adhesive protein, the Janus porous membranes are fabricated by the air-gating mechanism with distinct hydrophilic-hydrophobic interface. The water wetted hydrophilic surface could protect (liquid-gating) the leaking of the infused F-oil (lubricant oil) in the hydrophobic layer (F-free-membrane) on the cross-filtration process.306
