Synthesis of polydopamine coated tungsten oxide@ poly(vinylidene fluoride-co-hexafluoropropylene) electrospun nanofibers as multifunctional membranes for water applications

A Simple Approach to Fabricate Composite Ceramic Membranes Decorated with Functionalized Carbide-Derived Carbon for Oily Wastewater Treatment

“…During dope solution preparation, various porous additives are added to the polymer dope solutions leading to mixed matrix membranes (MMMs). The porous additives that are used in the fabrication of ultrafiltration MMMs include clays such as bentonite, conjugated microporous polymers, marshmallowlike gels, nanowires, nanomaterials such as TiO 2 , carbon nanotubes (CNTs), tungsten oxide (WO 3 ) nanoparticles, Pluronic F127, SiO 2 , CaCO 3 manganese dioxide (MnO 2 ) and graphene [17][18][19][20][21]. In their recent work, Mavukkandy et al fabricated new MMMs by incorporating WO 3 nanoparticles into the PVDF-HFP polymeric membrane, leading to the development of a WO 3 @PVDF-HFP membrane [18].…”

To enhance the oil/water separation performance of WO 3 @PVDF-HFP, the membrane was coated with polydopamine resulting in 97.6% oil rejection under gravity filtration with a permeate flux of 384.3 LMH.…”

“…3e–i), relatively uniformly-distributed C, N, and O elements mapping could be observed on the surface of PDA@CF NWs. 26 The corresponding EDX pattern illustrated a strong signal of N element with a content of 4.5 wt%.…”

Facile fabrication of electrospun g-C3N4/Bi12O17Cl2/poly(acrylonitrile-co-maleic acid) heterojunction nanofibers for boosting visible-light catalytic ofloxacin degradation

“…1–3 The electrospun nanomaterials possess many advantages, including high porosity, high surface area to volume ratio, good thermal stability, good connectivity, tunable wettability, fine flexibility, easy fabrication and functionalization, and therefore, more and more researchers have paid attention to their fabrication and applications for sensing, air filtration, water purification, heterogeneous catalysis, environmental protection, energy harvesting/conversion/storage, drug delivery/release, biomedical engineering, and so on. 1–8 At present, some E-spun photocatalytic materials (E-spun PCMs) such as electrospun Bi modified BiVO 4 , 8 polyvinylpyrrolidone/poly(vinylidene fluoride)/TiO 2 , 9 TiO 2 /g-C 3 N 4 , 10 graphene oxide/MIL-101(Fe)/poly(acrylonitrile- co -maleic acid), 11 pea-like TiO 2 @GO, 12 Pd decorated polydopamine-SiO 2 /PVA, 13 β-FeOOH/TiO 2 , 14 and polydopamine-coated tungsten oxide@poly(vinylidene fluoride- co -hexafluoropropylene) 15 have been developed and applied in the removal of organic pollutants from environmental water samples. These reported results demonstrated that the E-spun PCMs were efficient, stable, and easily recoverable photocatalysts for pollutant degradation, 9–15 and thus more novel E-spun PCMs are desired for pollutant removal.…”
