A model is developed for the nonsolvent vapor-induced phase separation process (VIPS). The model incorporates coupled heat and mass transfer, ternary diffusion and a moving boundary at the polymer solution/air interface. Predictions are shown for mass transfer paths, composition profiles, film tempe

Kinetics of phase separation of polymer solution layers induced by nonsolvent vapor was investigated. Polymer solutions were prepared with polysulfone (PSF) and N-methyl-2-pyrrolidinone (NMP) as a solvent. The phase separation was induced by exposing the solution layers to controlled water vapor. Us

Phase separation of poly(vinylidene fluoride) dimethylformamide solution was induced by the penetration of water vapor, and the porous membrane was formed. As the humidity in the gas phase increased, membrane morphology changed in the order of dense, porous (cellular), and lacy-like structures. At t

The isothermal phase diagram for poly(vinylidene fluoride)/dimethyl formamide/water system was derived. The binodal and spinodal were calculated based on the Flory-Huggins theory and the calculated binodal was approximately in agreement with the experimental data of the cloud points. The isothermal
