“…For instance, the zwitterion material used in this study, sulfobetaine methacrylate (SBMA), has an ammonium moiety (NH 4+ ) and a sulfite group (SO 3− ), and they can bond with eight water molecules employing electrostatic cooperation without significant induced stretching [ 37 ]. A few common techniques, such as biomimetic bonds [ 38 ], joining[ 17 , 39 ], mixing [ 40 ], interfacial polymerization [ 36 ] and surface throwing [ 34 ] can enable the effective preparation of adjusted zwitterion into the layers. In other surface-adjustment strategies, mixing is progressively more viable for layer change for a few reasons: there is no pre-treatment required, it is a straightforward activity, and the resultant film exhibits incredible solidity.…”

Superhydrophilic zwitterions on the membrane surface have been widely exploited to improve antifouling properties. However, the problematic formation of a <20 nm zwitterionic layer on the hydrophilic surface remains a challenge in wastewater treatment. In this work, we focused on the energy consumption and time control of polymerization and improved the strong hydrophilicity of the modified polyvinylidene difluoride (PVDF) membrane. The sulfobetaine methacrylate (SBMA) monomer was treated with UV-light through polymerization on the PVDF membrane at a variable time interval of 30 to 300 s to grow a poly-SBMA (PSBMA) chain and improve the membrane hydrophilicity. We examined the physiochemical properties of as-prepared PVDF and PVDF–PSBMAx using numeric analytical tools. Then, the zwitterionic polymer with controlled performance was grafted onto the SBMA through UV-light treatment to improve its antifouling properties. The PVDF–PSBMA120s modified membrane exhibited a greater flux rate and indicated bovine serum albumin (BSA) rejection performance. PVDF–PSBMA120s and unmodified PVDF membranes were examined for their antifouling performance using up to three cycles dynamic test using BSA as foulant. The PVDF-modified PSBMA polymer improved the antifouling properties in this experiment. Overall, the resulting membrane demonstrated an enhancement in the hydrophilicity and permeability of the membrane and simultaneously augmented its antifouling properties.

“…Fluoropolymers like polyvinylidene fluoride (PVDF) has the advantages of high temperature resistance, chemical corrosion resistance, aging resistance and high strength due to stable -C-F bond in the main chain [60]. But the PVDF membrane application in the field of water treatment and separation is limited because of the strong hydrophobicity and easy pollution.…”

“…Zhang et al prepared PDA/RGO/Ag3PO4/PVDF membrane, which can efficiently degrade and separate dye molecules (99% removal of MB) under visible-light irradiation. Polydopamine has good absorption ability to ultraviolet and visible light, and its good photoconductivity can enhance the generation of photogenerated e -/h + under the visible light irradiation[60].…”

Heterogeneous photocatalysis is a technology widely applied to water puriﬁcation and wastewater treatment under ultraviolet (UV) or even sunlight irradiation for the removal of a variety of environmental pollutants into harmless species. Application of membrane for immobilization of semiconductors and their suitability in photocatalytic degradation of dyes have recently been developed. Integration of photocatalysis with membrane processes signiﬁcantly improve the membrane separation performance with reducing membrane fouling and improving permeate quality. This paper reviews recent progress in the photocatalytic membranes for wastewater treatment and water puriﬁcation with an emphasis on the type of membranes, membrane fabrication, and applications in pollutant removal.

“…These techniques have proven to be a reliable and excellent alternative to conventional treatment techniques in wastewater treatment [2][3][4][5]. They offer environmental safety, high separation efficiency, low energy consumption, and easy maintenance compared to other conventional separation processes making them an outstanding option for wastewater treatment, operating either alone or within a hybrid process [6][7][8]. Although membrane techniques play an important role in wastewater treatment, fouling still limits their use in many applications.…”
