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