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 snowed, 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 (Tg) showed an average decrease of 36°C when the membranes were plasticized. Finally, these membranes were tested as ionexchange materials of a gold-iodide complex.
