NAFION(R) ADSORPTION ANION TRANSFER AT THE INTERFACE BETWEEN 2 IMMISCIBLE ELECTROLYTE-SOLUTIONS (ITIES)

The adsorption/transfer of the perfluorosulphonate ionomer Nafion(R) a t the interface between two immiscible electrolyte solutions, (ITIES) is studied by cyclic voltammetry. The transfer of two adsorbed forms i s observed and it is postulated that these two forms correspond to a m orphological difference associated with the adsorption of Nafion(R) in the mixed solvent layer. Thermodynamic data are calculated for the tw o transferring forms. The observable transfer of the SO3CF3- (triflate ) anion, which is structurally representative of Nafion(R)'s polymeric backbone, confirms the feasibility of the transfer process presented.
