New Understanding of the Difference in Filtration Performance between Anatase and Rutile TiO<sub>2</sub> Nanoparticles through Blending into Ultrafiltration PSF Membranes

The blending of nanomaterials into a polymeric matrix is a method known for its ability, under certain circumstances, to lead to an improvement in membrane properties. TiO<sub>2</sub> nanoparticles have been used in membrane research for the last 20 years and have continuously shown prom...

description	The blending of nanomaterials into a polymeric matrix is a method known for its ability, under certain circumstances, to lead to an improvement in membrane properties. TiO<sub>2</sub> nanoparticles have been used in membrane research for the last 20 years and have continuously shown promise in this field of research. Polysulfone (PSf) membranes were obtained through the phase inversion method, with different TiO<sub>2</sub> nanoparticle concentrations (0, 0.1, 0.5, and 1 wt.%) and two types of TiO<sub>2</sub> crystalline structure (anatase and rutile), via the addition of commercially available nanopowders.
