Description:
The preparation and analysis of inorganic-organic polymer nanocomposites consisting of inorganic nanowires and multiwire "cables" in a random-coil organic polymer host is reported. Dissolution of inorganic (LiMo3Se3)n wires in a strongly coordinating monomer, vinylene carbonate, and the use of a rapid polymerization in the presence of a cross-linking agent produce nanocomposites without phase separation. Polymerization of dilute solutions yields a material containing mostly (Mo3Se3(-))n mono- and biwires, 6 to 20 angstroms in diameter and 50 to 100 nanometers long. Polymerization of more concentrated liquid crystalline solutions yields a nanocomposite containing oriented multiwire cables, 20 to 40 angstroms in diameter and up to 1500 nanometers long, that display optical anisotropy and electrical conductivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Golden -- DiSalvo -- Frechet -- Silcox -- Thomas -- Elman -- New York, N.Y. -- Science. 1996 Aug 9;273(5276):782-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.
