Summary
By varying the concentration of formamide within the acetone solutions from which cellulose acetate membranes were fabricated, a series of membranes exhibiting a wide range of performance characteristics was prepared. The morphological, optical, swelling and water transport properties of these membrane gels have been interpreted with reference to a phase inversion in their sol precursors.
Zusammenfassung
Aus Acetonlösung mit unterschiedlichem Gehalt an Formamid wurden Zellulosemembranen dargestellt. Die Eigenschaften der Membranen sind je nach den Konzentrationen des Formamids verschieden. Die Unterschiede werden durch Phasenänderungen während des übergangs Sol-Gel erklärt.
