Polypyrrole based cation transport membranes

It has been recently reported that the cation transport can be induced acro ss a conducting polymer membrane by the application of a potential gradient . As an extension of that work this article, is a part of an ongoing study to look at the effects of altering various parameters employed in the synth esis of the membranes, on the physical characteristics and cation transport properties of the resulting membranes. The results indicated that the opti mal film growth was achieved when using a growth temperature at or below 20 degrees C, a current density between 1 and 3 mA/cm(2), and a dopant concen tration of 0.1 M.
