Transport properties of hybrid perfluorinated membranes MF-4SC volumetrically modified using halloysite nanotubes

Abstract

The transport properties of new hybrid materials for fuel cells and catalysis based on sulfacationic
membrane MF-4SC and halloysite nanotubes are studied. Physico-chemical characteristics of hybrid
membranes were calculated from the experimental data of NaCl solutions diffusion through the membrane
into the water using the Nernst-Planck approach and the least square method. To clarify the results of
calculations we can take into account both the diffusion layers. It is shown that adding halloysite nanotube
into a bulk matrix of the perfluorinated membrane markedly affects their exchange capacity as well as
structural and transport properties of modified membranes.
