A new approach to improve antifouling property of PVDF membrane using in situ polymerization of PAA functionalized TiO2 nanoparticles

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

“…Fig.5 depicts the effect of different parameters on the flux of neat and modified membranes. Furthermore, Madaeni et al [89] compared self-assembling and grafting techniques and concluded that grafting from method in which functionalizing of TiO 2 on the surface of PVDF membrane via acrylic acid monomers prior than in situ grafting polymerization of the blend solution, caused better dispersion of TiO 2 NPs on the membrane surface ( Fig.6). Additionally, some studies investigated the membrane performance in bioreactore [84,90,91] and also evaluated the effect of homogeneous dispersion of TiO 2 NPs on the membrane surface [92], and pH [93] on the fouling mitigation, as well as hydrophilicity enhancement via grafting TiO 2 nanoparticles with acrylic acid groups on the membrane surface [94].…”

Titanium dioxide nanotubes embedded mixed matrix PES membranes characterization and membrane performance

“…In addition, the antifouling properties for the membrane can be modified by blending with inorganic nanoparticles such as Al 2 O 3 , SiO 2 , TiO 2 , Fe 3 O 4 , and carbon nanotubes [28][29][30][31]. In recent years, TiO 2 nanoparticles blend membranes have been fabricated by precipitating the nanoparticles on the surface of the porous membranes [3,32] or blending them with polymeric casting solution [14,33].…”

Hydrophilicity and crystallization behavior of PVDF/PMMA/TiO2(SiO2) composites prepared by in situ polymerization

“…PVDF/PMMA/TiO 2 (SiO 2 ) composites were generated after in situ polymerization. Many researchers have prepared polymer/inorganic composites by in situ polymerization, and they have found that the dispersion of the nanoparticles in the polymer matrix achieved by in situ polymerization is more uniform than that achieved by a self-assembly procedure [23]. In this work, the dispersion of TiO 2 (SiO 2 ) in the composite matrix was characterized by scanning electron microscopy (SEM).…”
