Abstract

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.
