of the operating pressure of the membranes compared to pure PVC

membranes with best properties obtainable at a blend composition of 75:25 (PVC:TPU). The

performance of blend membranes was examined in the removal of Coomassie Brilliant Blue G-250 dye...

the aqueous solution. The blended membranes exhibited higher hydrophobicity and separation factor as well as lower permeability in comparison with the pure PEBA membrane. The blended membrane that was prepared at PEBA/PVDF ratio of 95/5 was found...

Due to favorable interactions between Polyvinyl chloride (PVC) and Thermoplastic Polyurethane (TPU) chain segments as revealed by viscosity measurement and differential scanning calorimetry (DSC), the ternary phase diagram ...

showed that the blend of two polymers was highly incompatible

even in their common DMF solvent. However, this

incompatibility led to a remarkable increase in the porosity

of the blend membrane and pure water flux compared

to those for pure...

formation. The blend membrane showed lower rejection than pure PVC membrane, due to the change of surface morphology by adding PAN to PVC....
