Abstract
A two-step adsorption process for producing ordered organic/inorganic multilayer structures is provided. Multilayered films are formed on metallic and nonmetallic substrates by alternate adsorption of a cationic polyelectrolyte and anionic sheets of a silicate clay. The two-step adsorption process is not only fast but allows also for preparation of multilayer elements of thicknesses greater than about 2200 Angstroms on silicon, and greater than about 1500 Angstroms on gold, silver, and copper.
