Abstract

In this study, magnesium-aluminum (Mg-Al) based LDHs with different Mg2+/Al3+ ratios were prepared by co-precipitation method and modified with perfluorooctane-sulfonic acid tetraethylammonium salt (PFOSA). X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Fourier Transfer Infrared spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) were carried out to obtain the structural and thermal characteristics of resulting materials. The organo-modified LDHs have been used in the formulation of Nafion® nanocomposites. Nanocomposite membranes were prepared by casting of LDH/PFOSA nanoparticles dispersed in Nafion® solution. Then, modified LDH/Nafion composite membranes were evaluated for water retention capability at ambient and elevated temperature.
