PVDF-TiO₂coated microfiltration membranes: preparation and characterization

Photocatalytic membrane reactors for water treatment

“…Ten types of polymeric membranes (Table 7.3) were subjected to the initial UV screening test. Among these ones, blending with inorganic materials, especially nanoparticles, has attracted great attention owing to the relatively easy preparation by the method of phase inversion, which is carried out under mild conditions (Shon et al, 2010;Wei et al, 2011). However, in a study of the oxidative stability of membranes (under UV, hydrogen peroxide [H 2 O 2 ], and combined UV/H 2 O 2 conditions), it was found that the stability of PAN membrane declined considerably when it was exposed to 10 days of 200 mM H 2 O 2 /UV conditions.…”

Application of Colloidal Precipitation Method Using Sodium Polymethacrylate as Dispersant for TiO2/PVDF Membrane Preparation and Its Antifouling Properties

“…Among different nanoparticles, titanium dioxide (TiO 2 ) has received much attention because of its stability, availability and stronger chemical resistance to acids and bases compared with other metal oxides as well as its potential antifouling abilities [11,12]. There are different approaches for fabrication of TiO 2 nanocomposite membranes among them are; blending the nanoparticles into the membrane matrix [7,[13][14][15][16][17] and coating nanoparticles on the membrane surface [6,[18][19][20].…”
