Evaluation of the antifouling and photocatalytic properties of poly(vinylidene fluoride) plasma-grafted poly(acrylic acid) membrane with self-assembled TiO2

TiO2 nanocomposite based polymeric membranes: A review on performance improvement for various applications in chemical engineering processes

“…According to Rakap et al [148], the Pd catalyst supported on TiO 2 modified membrane showed great effect on portable hydrogen generation systems. On the other hand, You et al [149] utilized plasma-grafting method in order to prepare functional groups on the surface of PVA/PAA membrane to stabilize TiO 2 nanoparticles via self-assembly method.…”

Surface engineering and self-cleaning properties of the novel TiO2/PAA/PTFE ultrafiltration membranes

“…Also, the carboxyl groups in PAA would, in turn, provide sufficient bonding sites for inorganic oxide nanoparticles [19]. This strategy was successfully applied in coating TiO 2 on polyvinylidene difluoride (PVDF) membrane using TiO 2 nanoparticles [20] or solgel [21], however, the mechanical stability and recycling application were not presented therein.…”

Preparation of photo-catalytic copolymer grafted asymmetric membranes (N-TiO2-PMAA-g-PVDF/PAN) and their application on the degradation of bentazon in water

“…In the spectrum of PMAA-g-PVDF the peaks located at 1270 and 1000 cm −1 are ascribed to the stretching vibrations of -C-O of the -COOH group and these peaks indicate the successful grafting of PMAA to PVDF. The medium peak at 1139 cm −1 is ascribed to the C-O-C stretching vibrations consistent with the group formed with the graft reaction [25,27,28]. 1 H and 13 C spectra were acquired to elucidate the structure of PMAA-g-PVDF and also to confirm successful grafting of PMAA onto PVDF polymer chains.…”

“…The spectrum of PVDF homopolymer has peaks at 1410, 1180 and 1075 cm −1 that can be attributed to the C-F deformation vibrations [24]. The peaks at 3023 and 2981 cm −1 are attributed to the -CH 2 (methylene group) anti-symmetric and symmetric stretching vibrations, respectively [25,26]. The peaks are superimposed on the O-H vibrations of PMAA with a band between 2500 and 3500 cm −1 .…”
