Construction of superhydrophilic and underwater superoleophobic membranes via in situ oriented NiCo-LDH growth for gravity-driven oil/water emulsion separation

The development of superhydrophilic/underwater superoleophobic membrane is significant for purification of emulsified oily wastewater. However, low flux and membrane fouling still remains a challenge. Herein, a sisal-like structured hybrid membrane is prepared through in situ growth of nickel cobalt layered double hydroxide (NiCo-LDH) microcrystals on membrane surface for oil/water emulsion separation. The as-prepared hybrid membrane ([email...
