Abstract

Four lots of cellulose acetate (CA) membranes, modified with polyacrylic acid, using various plasticizers, and coated with polyaniline (PANI) were prepared. The morphology of the membranes was evaluated by using scanning electron microscopy, and the membranes showed larger pore size when the plasticizers were used. The electrical conductivity of the modified membranes and coated with PANI increased by two orders of magnitude when the plasticizer triphenyl phosphate was used. The strain at break improved by an order of magnitude and the glass transition temperature (T~g~) showed an average decrease of 36°C when the membranes were plasticized. Finally, these membranes were tested as ion‐exchange materials of a gold‐iodide complex. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

The interaction between solutes and semipermeable membranes is an important factor for the membrane-separation process. As an extension to previous works, we studied the adsorption properties of cyclic compounds on cellulose acetate, a material commonly used for semipermeable membranes, in aqueous s

## Abstract Hydrophilic ultrafiltration membranes have been prepared by blending cellulose acetate (CA) as a matrix polymer with increasing concentrations of poly(vinylpyrrolidone) (PVP) using __N,N′__‐dimethylformamide as the solvent. It is observed that the presence of PVP beyond 50 wt % in the c
