Description:
Living organisms construct various forms of laminated nanocomposites through directed nucleation and growth of inorganics at self-assembled organic templates at temperatures below 100°C and in aqueous solutions. Recent research has focused on the use of functionalized organic surfaces to form continuous thin films of single-phase ceramics. Continuous thin films of mesostructured silicates have also been formed on hydrophobic and hydrophilic surfaces through a two-step mechanism. First, under acidic conditions, surfactant micellar structures are self-assembled at the solid/liquid interface, and second, inorganic precursors condense to form an inorganic-organic nanocomposite. Epitaxial coordination of adsorbed surfactant tubules is observed on mica and graphite substrates, whereas a random arrangement is observed on amorphous silica. The ability to process ceramic-organic nanocomposite films by these methods provides new technological opportunities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aksay -- Trau -- Manne -- Honma I -- Yao -- Zhou -- Fenter -- Eisenberger -- Gruner -- New York, N.Y. -- Science. 1996 Aug 16;273(5277):892-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The authors are at Princeton University, Princeton, NJ 08544-5263, USA.
