Effect of TiO2 nanoparticles on the surface morphology and performance of microporous PES membrane

Synthesis and characterization of novel hybrid polysulfone/silica membranes doped with phosphomolybdic acid for fuel cell applications

“…This fact shows that SiO 2 particles act as reinforcing agents for very low amount of particles and can be related with an interaction between SiO 2 and sulfonated matrix which results in the formation of crosslinked network within the polymer matrix. This interaction produces an enhance of the energy of breaking down of the polymer main chains [12]. At the highest concentration, the excessive oxide content produced a weakness of both properties tensile strength and % elongation of sPSU [19].…”

“…Hybrid organic inorganic nanocompo sites have gained considerable attention because present improved properties such as swelling capacity, water retention or operating temperature, while maintaining mechanical proper ties [8 10]. In this line, there are several studies that reflect the improvement of performance of several polymers due to the incorporation of inorganic particles such as SiO 2 [11], TiO 2 [12] or zeolites [13]. Also, another inorganic fillers such as heteropo lyacids like phosphotungstic (PWA), phosphomolybdic (PMoA), silicotungstic (SiWA) and silicomolybdic (SiMoA) acids related to the well known Keggin structure, have recently received most attention due to their good proton conductivities [14 17].…”

Investigation of Titanium-Dioxide Coatings on Membrane Filtration Properties

“…TiO 2 is favoured over other semiconductors due to its good physical and chemical properties, availability, photocatalytic activity, desirable hydrophilic and potential antifouling properties [5][6][7]. PES composite membrane modified by self-assembly of TiO 2 nanoparticles showed good separation qualities and higher water flux compared to the unmodified membrane, improved thermal stability, and increased hydrophilicity [2,8]. Three different modified PES membranes were compared by Rahimpour and co-workers [1]: TiO 2 -entrapped membranes, UV-irradiated TiO 2 -entrapped membranes, and UV-irradiated TiO 2 -deposited membranes.…”

Verification Stability of Anion-Exchange Membrane with Surface Modification with Application in Electrodialysis Process

“…It was used, for example, to prepare a TiO 2 microporous membrane [13] for the preparation of a nanofiltration membrane containing GO (graphene oxide) [14]. PES membranes are used in electrochemical processes [15][16][17][18].…”
