Theoretical estimation of conductivity of ion-exchange membranes taking into account to spatial orientation of conducting phases

详细

The conductivity of ion-exchange membranes are theoretically assessed in a wide range of concentration of equilibrium electrolyte solutions with the use of the power equation of the two-phase model of conduction. A relationship is revealed between the parameter characterizing the spatial orientation of membrane’s conducting phases and the solution concentration range allowing the adequate description of membrane conductivity. The approach proposed is checked based on experimental concentration dependences of the conductivity of ion-exchange membranes of different structural types.
