Abstract: |
|
The PVDF/BC blend membranes were prepared by adding bacterial cellulose (BC) and BC/SiO2 composites by means of phase separation method. Membrane structures and properties were characterized by Scanning Electron Microscope (SEM) and membrane performance tester. The water flux was improved by the addition of BC, but the retention rate decreased. When the BC content is around 0.4%, the blend membrane got the better performance. In the PVDF/BC/SiO2 blend membranes, BC/SiO2 composites were added. In this case, the water flux decreased, while the retention rate was increased. |
