Abstract
Fabricating membranes with superior antifouling property and long-term high performance is in great demand for efficient oil-water separation. Herein, we reported a reaction enabled surface segregation method for antifouling membrane fabrication, in which the pre-synthesized fluorinated ternary copolymer Pluronic F127 was coordinated with Ti4+ as segregation additive in the membrane casting bath. Additionally, tannic acid was utilized to enhance the self-assembly of the copolymer in the coagulation bath, and freshly-biomineralized TiO2 was anchored into the membrane surface through hydrogen bond. A hydrogel layer was constructed onto the membrane surface with synergistically tailored heterogeneous chemical composition and heterogeneous geometrical roughness. The dual-heterogeneous membrane exhibited hydrophilic and underwater superoleophobic features, resulting in high water flux (621.7 L m-2 h-1) at low operation pressure of 0.05 MPa and an excellent antifouling property (only 4.8% flux decline during 24-hour filtration). In situ reaction enabled surface segregation method will accelerate the development of antifouling membranes for oil-in-water emulsion separation.

Abstract
Developing novel biomaterials integrating robustness and multitasking separation performance are of importance. However, those were limited in application due to the expensive, time-consuming and complex fabrication process. In this work, with the inspiration from high porosity and surface area of natural materials, the porous superhydrophobic melamine sponges (SMS) coated hydrophobic TiO2 and epoxy copolymer were fabricated via a facile, inexpensive, eco-friendly and large-scale strategy. The SMS showed excellent superhydrophobic property, and could well resist the harsh mechanical damage, chemical corrosion, extreme temperature, and irradiation of UV without losing antiwetting ability. Besides, it displayed selective oil absorbing ability, recyclability, and self-cleaning ability. Moreover, the SMS displayed superior multitasking performance for continuous oil/water separation, surfactant-stabilized O/W emulsions separation (separation efficiency above 99%), and bacterial/fungus containing filtration (filtration efficiency over 60% for S. aureus, 90% for E. coli and C. albicans). With the multifaceted features, the SMS is a promising sponge material for treatment of industry oily or bacterial/fungus-containing wastewater in practical application.

Abstract
Membrane separation technology is one of the best methods to deal with wastewater released from oil spills and industrial wastewater. Therefore, we designed and prepared hydroxyl-rich titanium carbide MXene materials and filtered them onto a commercial polyvinylidene fluoride substrate membrane to obtain a cracked-earth-like MXene membrane with abundant hydroxyl groups and excellent underwater wettability. The underwater oil contact and sliding angles were approximately 157° and less than 3°, respectively. Moreover, the membrane effectively separated a variety of surfactant-stabilized stable emulsions with a high permeation flux of up to 6385 L m-2h-1 bar-1 and offered adequate performance after five cycles of the separation experiment. Additionally, the membrane exhibited remarkable resistance toward corrosive chemicals without any decrease in its underwater wettability performance. For example, the membrane was used to separate the emulsions containing alkali, salt, and acid. This study provides a new strategy to resolve the oily wastewater disposal problem by fabricating a cracked-earth-like MXene membrane with abundant hydroxyl groups.

Abstract
Superhydrophilic membranes with simultaneous underwater superoleophobicity are highly desirable and worth exploring for separation of emulsified oil from water. In this work, combining the strong negative charges of phytic acid (PA) and the high cationic charge density of polyethyleneimine (PEI), an eco-friendly PA@PEI polyelectrolyte complex was synthetized in aqueous solution. And then the polyelectrolyte complex was deposited onto hydrophobic PVDF membranes through a one-step assembly approach with high convenience, endowing the membranes with superhydrophilic and underwater superoleophobic property. The as-prepared PA@PEI/PVDF membrane shows outstanding static and dynamic water stability, and was successfully used to separate multiple oil-in-water emulsions, with an average rejection rate exceeding 98.5% and a water flux up to 12203.6 L m-2∙h-1∙bar-1. Furthermore, the water flux can be recovered to a high level after four separation-washing cycles, showing excellent antifouling performance and recovery capability. Together with its natural raw materials and environmentally friendly preparation strategy, the PA@PEI/PVDF membrane shows great potential in practical treatment of emulsified oily wastewater.

Abstract
A new NiAlFe layered double hydroxide/polydopamine/polyvinylidene fluoride (NiAlFe LDH/PDA/PVDF) membrane was fabricated by in-situ growth of LDH on the PDA modified PVDF membrane. The as-prepared membrane possesses a nano/microscale rough structural surface and displays the superior wettability of superhydrophilicity in air and underwater superoleophobicity. Combining the favourable features of superwettability and hierarchical rough structure, the NiAlFe LDH/PDA/PVDF membrane could effectively separate a series of oil-in-water emulsions with high efficiency (>99%) and high permeation flux (925-1913 L m-2 h-1 bar-1). Besides, owing to the light harvest ability of NiAlFe LDH, the relevant membrane also can be applied as a photocatalysis paper for the light-driven treatment of antibiotic residue in aqueous solution. In which, NiAlFe LDH/PDA/PVDF membrane can effectively degrade typical antibiotic tetracycline within 20 min under UV light irradiation, exhibiting excellent photocatalytic activity. In addition, cyclic experiments demonstrate that NiAlFe LDH/PDA/PVDF membrane has excellent stability and reusability both in oil-in-water emulsion separation and photocatalytic reaction. In general, the findings of this research demonstrate that photo-response LDH modified membranes have potential multiple applications in wastewater treatment.
