TRANSPORT ACROSS STAND-ALONE CONDUCTING POLYPYRROLE MEMBRANES CONTAINING DODECYL-SULFATE COUNTERIONS

The modification of the electrodynamic transport properties of conduct ing polypyrrole membranes by the use of dodecylsulfate anions during p olymerization has been demonstrated. The use of small amounts of the s urfactant counterion in combination with paratoluene sulfonate as the predominant anion during polymerization allows the production of condu ctive, mechanically stable materials with differing chemical propertie s. This, in turn, influences the transport characteristics and has bee n found to induce asymmetric transport character in the membrane.
