Influence of Additives and preparation Conditions on PVDF Membrane Morphology

摘要

Polyvinylidene difluoride(PVDF) is a hydrophobic polymer with excellent chemical-inert property.It can be solved by some solvents and prepare microporous membrane by the phase-inversion method.A lot of researchers focus their attention on the formation mechansim of PVDF membranes in order to improve its separation property.
