Abstract

In the recent research, 𝑃𝐸𝑠−𝑇𝑖𝑜2 are made by the phase-inversion method by the method of casting the solution. In this method, polyvinylpyrrolidone (PVP) was used as a pore former and N-N dimethyl acetamide (DMAC) as a solvent, and nanoparticle 𝑇𝑖𝑜2 was utilized as additive in membrane fabrication. Water permeability and salt Rejection tests, and water content and water contact angles were used to describe the membrane. Water flux was enhanced sharply by utilizing 𝑇𝑖𝑜2. By using the nanoparticle 𝑇𝑖𝑜2 to the solution, the salt rejection increased sharply and improved with the use of nanoparticles 𝑇𝑖𝑜2. the water content increased by applying more than 0.05 wt% of the nanoparticles 𝑇𝑖𝑜2 and then decreasing. The water contact angle also decreased.
