Superhydrophobic and superoleophilic porous boron nitride nanosheet/polyvinylidene fluoride composite material for oil-polluted water cleanup

Superhydrophobic and superoleophilic porous BNNS/PVDF composite material can be fabricated by formation and freeze-drying of a gel. The resultant composite material can be efficiently used to separate insoluble oil from water. Most importantly, such composite material is stable and durable making it a promising candidate for oil-polluted water treatments.
