TL;DR: A two-step adsorption process for producing ordered alternating ultrathin layers of organic (14) - inorganic (16) multilayer structures was proposed in this article. But the two-stage process was not fast enough for preparation of multi-layer elements of thicknesses greater than about 2200 Angstroms on silicon, and greater than approximately 1500 Angstromm on gold, silver and copper.
Abstract: A two-step adsorption process for producing ordered alternating ultrathin layers of organic (14) - inorganic (16) multilayer structures (10). Multilayered films are formed on metallic and nonmetallic substrates (12) by alternate adsorption of a cationic polyelectrolyte and anionic sheets of a silicate clay. An open space (18) represents the packing imperfection or boundaries in a hectorite layer between two organic layers (14). 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.

TL;DR: In this paper, the effects of the composition, such as the amounts of clay, polymer, and water content in DMAA-NC gels, on the tensile mechanical properties were investigated in detail.
Abstract: Nanocomposite type hydrogels (DMAA-NC gels) consisting of organic (polymer)/inorganic (clay) networks were prepared by in-situ free-radical polymerization of N,N-dimethylacrylamide (DMAA) in the presence of inorganic clay in aqueous solution. The composition of the NC gels could be controlled directly by altering the composition of the initial reaction mixture. The resulting DMAA-NC gels were mostly uniform and transparent, irrespective of their clay and polymer contents. From DSC, X-ray, TEM, and tensile mechanical measurements, the network structure was established. Contrary to conventional chemically cross-linked hydrogels (DMAA-OR gels) prepared by chemical cross-linking with a difunctional monomer, DMAA-NC gels exhibit superb mechanical properties with astonishingly large elongations at break, near to or greater than 1500%. The effects of the composition, such as the amounts of clay, polymer, and water content in DMAA-NC gels, on the tensile mechanical properties were investigated in detail. With inc...
