Effect of external coagulation conditions on property of five-hole blend membrane
The effects of some external coagulation conditions on the property of five-hole Poly(vinylidene fluoride)(PVDF)/poly(vinyl chloride)(PVC)/poly(methyl methacrylate)(PMMA) blend membrane were studied. Dimethylacetamide (DMAC) and polyvinyl pyrrolidone (PVP) were used as solvent and additive respectively. The external coagulation conditions investigated in the work were the coagulation temperature and the DMAC content in coagulation bath. The result showed that the flux increases along with the increase of coagulation bath temperature and could reach the maximum at 35 , then decrease gradually. The effect of the DMAC content in coagulation bath on flux ℃ is very similar to that of the temperature. The cross-sectional structures were examined by scanning electron microscopy.
