PROPERTIES OF FLAT-SHEET ASYMMETRIC POLYSULFONE MEMBRANES OBTAINED BY THE PHASE INVERSION METHOD USING VARIOUS COAGULANTS
Abstract
The formation of polymeric membranes with the desirable structure and properties requires consideration of the influence of a number of factors In this work, in order to understand the thermodynamics of the deposition process of membranes from polysulfone (PSF), triple phase diagrams were studied. The morphology and gas separation properties of flat-sheet asymmetric PSF membranes obtained by the phase inversion method using various coagulants were also investigated.
