Abstract
In this paper, we present a new electrochemical method for measuring the water vapor transmission rate, the permeability coefficient and the diffusion coefficient of polymer membranes. This method is based on the electrical conductivity of an electrolyte layer, which depends on the water content inside the layer. We describe the calibration process and show exemplary measurements on polymer membranes in good agreement with literature values.
