Journal ArticleDOI
The formation mechanism of asymmetric membranes
TL;DR: Aromatic polyamide asymmetric "skin type" membranes have been prepared by the Loeb-Sourirajan technique as mentioned in this paper, and two different structures were obtained, depending on the rate of precipitation.

A rationale for the preparation of Loeb-Sourirajan-type cellulose acetate membranes
TL;DR: In this paper, an attempt has been made to rationalize the variables in the preparation procedure of Loeb-Sourirajan-type reverse-osmosis membranes and the porosity of the membrane has been ascribed to the relative rates of water entering and solvent leaving the cast film.
Journal ArticleDOI
Concerning the microstructure of dry‐RO membranes
TL;DR: The microstructure of cellulose acetate reverse osmosis membranes has been elucidated with the aid of scanning and transmission electron microscopy in this paper, showing that the gel morphology of each of these layers originates in its sol precursors within the nascent membrane which manage to survive the sol gel transition intact.

The mechanism for formation of “skinned” membranes
TL;DR: In this article, the critical water concentrations required for initiating precipitation of cellulose acetate from 20% solutions in acetone, dioxane, acetic acid, triethyl phosphate (TEP), dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO) have been determined.
