Study on Preparation and Properties of PVDF/PVC/PMMA Blend Hollow Fiber Membrane
The preparation of PVDF/PVC/PMMA blended membrane and its properties were investigated and discussed. and the best conditions of preparing membrane were obtained. When the mass ratio of PVDF/PVC/PMMA was 7:1.2:1.8 and polymer concentration was 17％ and concentration of tween-80 was 6％ as additive, properties of the membranes appeared to be better. Following conclusions were drawn through the square- crossmg test. First of all, water flux of blend membranes was significantly influenced by the polymer concentration, while the mass ration of PVDF to PVC and PMMA was the most important factor affecting membrane strength. Whats more, less ingredient of PMMA resulted in the better hydrophilic of blended membrane.
