Abstract
Ionic transport through exchange membranes such as Nafion is controlled by the microstructure and charge of the ionomer. Transport and polymer morphology can be studied by restructuring the microenvironment of Nation by supporting it on Nuclepore polycarbonate membranes, which contain microdimensional cylinders, 0.015 to 0.6 μ m in diameter. Transport rates through the Nafion phase of the composites increase as the pore sizes decrease to 0.05 μ m. For 0.05 μ m pores, transport is an order of magnitude more facile than transport through unsupported (bulk) Nafion. The increased transport rates are ascribed to increased ordering of the microenvironment of Nafion and due in part to variation of extraction coefficients as the substrate pore sizes change
