Abstract: |
|
The miscibility of PVC/PVDF/PMMA blending system was investigated by the means of shearing viscosity. It was demonstrated that blended solution possessed partial miscibility. Then the dilute solution viscometry was used to determine the miscibility of all sorts of polymer blending ratio. PVC/PVDF/PMMA blend membranes were prepared by phase inversion. The micro-structure of blend membranes was analyzed by SEM and the water permeability, mechanical character and contact angle of blend membranes were measured too. The results showed that the water permeability, toughness, flexibility and the hydrophilicity of blend membranes were improved greatly compared to PVC membrane. It was obtained that both the permeability and tensile strength of blending membrane with the ratio of 6:1:3 were better. Therefore the optimizing blending ratio was 6:1:3. |
