Diffusion of solutions in the course of the matrix synthesis of composite membranes MF-4SC—polyaniline and their transport properties

The dependence of the kinetics of diffusion transfer of solutions through MF-4SC and MC-40 ion-exchange membranes during the matrix synthesis of polyaniline on the composition of feed solutions and the nature of the initiating agents and the polymer matrix is studied. The effect of the conditions of...

Description
Summary:The dependence of the kinetics of diffusion transfer of solutions through MF-4SC and MC-40 ion-exchange membranes during the matrix synthesis of polyaniline on the composition of feed solutions and the nature of the initiating agents and the polymer matrix is studied. The effect of the conditions of the modification of the parent membrane on the resultant physicochemical characteristics is studied. The conditions of synthesis for the preparation of MF-4SC—polyaniline (emeraldine) composites with an optimized combination of conducting and diffusion characteristics are found. The contribution of electron conductivity to the overall proton-electron conductivity of the composite films is estimated.
