A novel zwitterionic polyelectrolyte grafted PVDF membrane for thoroughly separating oil from water with ultrahigh efficiency
Abstract
Oil–water separation is a worldwide challenge because of increasingly oily wastewater, as well as frequent oil spill accidents. We report in this work the fabrication of a zwitterionic polyelectrolyte brush (poly(3-(N-2-methacryloxyethyl-N,N-dimethyl) ammonatopropanesultone), abbreviated as PMAPS)-grafted poly(vinylidene fluoride) (PMAPS-g-PVDF) membrane via a surface-initiated atom transfer radical polymerization (SI-ATRP) technique for separating oil from water. By tuning polymerization time, a superhydrophilic and underwater superoleophobic PMAPS-g-PVDF membrane was successfully prepared. The membrane can be applied for thoroughly separating dispersed oil from water with ultrahigh separation efficiency >99.999% in terms of rejection coefficient. The oil contents after one-time separation of a selection of oil–water mixtures are all less than 10 ppm and some of them are even lower than 2 ppm. These values are much lower than the standard minimum requirements of the international regulations for wastewater discharging. The oil-adhesion force between an oil droplet and the membrane surface was measured to be less than 1 μN. Due to the ultralow oil adhesion, the membrane exhibits an excellent antifouling property to oil and is easily recyclable.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
