โœฆ Synopsis

The effect of technological conditions for membrane-amking on the performance and the structure of PVC/PAN blended UF membranes has been studied. The results show that the miscibility of polymers blended has an important bearing on this effect. Only when the miscibility of polymers is better, a blended UF membrane with greatly improved flux or retention rate will be obtained by raising coagulating temperature or by adding a small amount of NaCl without excessive damage to other properties. But the extension of evaporation time always leads to a worse performance for PVC/PAN blended UF membranes.
