Abstract

Kvalitativno je predstavljen mehanizm nastajanja polimerne asimetrične porozne membrane po mokrem postopku fazne inverzije. Nastanek morfoloških značilnosti membran iz celuloznega acetata, polisulfona, polimetilmetakrilata,termoplastičnega poliuretana in poliamida 4,6 je interpretiran s `potmi sestave` v ternarnem faznem diagramu polimer/topilo:netopilo ter podprt z evidencami pojavov motnosti med nastajanjem membrane, skrčitve ulite raztopine polimera v (proto)membrano in s permeabilnostjo nastalih membran z vodo.

Secondary title: Mechanism of the polymer asymmetric porous membrane formation by wet phase inversion
Secondary abstract: The mechanism of polymeric asymmetric porous membranes prepared by the wet phase inversion process is qualitatively presented. The formation of the morphological characteristic features of membranes from cellulose acetate, polysulfone, poly(methylmetacrylate), thermoplasric polyuretane and polyamide 4,6 is interpreted in terms of the `composition path` in the ternary phase diagram polymer/solvent:nonsolvent and supported by evidences of turbidity phenomena taking place during membrane formation, shrinkage of the cast solution of polymer to the (proto)membrane, and water permeability of membranes.
