This work focused on the preparation of poly(vinyl alcohol) (PVA)/ silicate layers composites. Montmorillonite and organically modified montmorillonite (MMTTEA and MMTHDTMA) were used for the PVA nanocomposites. The membranes of poly(vinyl alcohol)/ modified montmorillonite composites were prepared by casting from a polymer/silicate (3wt%) water suspension. The preparation of the materials was influenced by hydrogen bonds and the hydrophobicity of the organophilic material. The obtained materials have different mechanical properties from the neatPVA. In all cases, the mechanical properties were improved.
