Abstract
Coagulation of a polysulfone solution film was induced by water vapour sorption under atmospheric exposure, followed by water diffusion in a coagulation bath. Demixing in the skin region of the solution film can involve both equilibrium and non-equilibrium phase separation. Surface pore size of the solidified film is proportional to the duration of the liquidliquid phase separation during vapour sorption.
