Triblock polymer template assisted sol-gel process for fabrication of multi-channel TiO2/ZrO2 ultrafiltration membrane

► The fabrication of multichannel anatase TiO2 membrane with an average pore size of 3.3 nm for ultrafiltration via a template assisted sol-gel process, using (EO)13(PO)30(EO)13 as a template to modify the properties of the sols and the membranes. ► The sample obtained from the sol containing L64 has larger average pore size of 3.7 nm, pore volume of 0.11 cm3 g−1 and specific surface area of 94.3 m2 g−1 than the corresponding properties of the sample from the sol without L64. ► The good separation performance of the resulted multi-channel TiO2 membrane indicates its potential applications in the enrichment or separation of proteins and polypeptide in industrial production.
