Abstract

A self-supporting, multilayered film which was prepared from an aqueous dispersion of montmorillonite and orthophosphoric acid (H3PO4) remained intact even in hot water and maintained the ion exchange capacity similar to that of the original montmorillonite powder. An ammonium surfactant (CTAB) was intercalated into this film readily to give a highly oriented composite film.
