| Abstract: | PVC/VC-co-VAc blend membranes were formed via phase inversion.The effects of polymer concentration,the ratio of blend components,the amount of additive,and the bi-component additives on membrane performances were discussed.The membrane morphology was characterized by SEM, and the mechanism of pore formation was also investigated. |
