| description | Flat sheet cellulose acetate membranes with asymmetric structure were prepared by a wet phase inversion process. In the preparation procedure of phase inversion membranes several parameters determining the structure and properties of the membrane were identified. These parameters are casting solution composition (polymer concentration), solvent evaporation period, precipitation bath composition, annealing temperature and room humidity. In this paper the effect of the first three parameters on the membranes formation were presented. The membranes are characterized in terms of their permeabilities by permeation cell. The membrane structures are studied using scanning electron micrographs. The results showed that polymer concentration, solvent evaporation periods and a precipitation bath composition significantly affect the membrane structures and performance. |
