Abstract

The technique of polyvinylidene fluoride(PVDF)pipe microporous films production has been studied.The influential factors in the preparation of pipe microporous films by phase transformation is discussed systematically.Th e study shows that the effect of casting solution temperature on the cutting of rate of PVDF pipe films and the pure water flux is not obvious.After adding NI-LC1 to the casting solution,the pure water flux of films gets higher,the cutting of rate gets lower and the aperture gets bigger.Th e PVDF pipe microporous films which are made by using diferent solidification baths are different.Th eir pure water flux and cutting of rate are diferent as well
