Fabrication and investigation of hydrophilicity, porosity, and water content of PVC/TPU blend membranes to be used in water purification

In this work, Polyvinylchloride (PVC)/Thermoplastic polyurethane (TPU) blend membranes with different loadings of TPU (۰.۷۵, ۱.۵۰, and ۲.۲۵) were fabricated by non-solvent induced phase separation (NIPS) method. To evaluate the hydrophilicity changes in blend membranes, a contact angle test was conducted. In addition, the effects of hydrophilicity on porosity and water content of membranes were investigated. Results illustrated that the water contact anlage decreased by increasing the content of TPU in casting solution leads to an excellent increment in porosity and water content of blend membranes.
