Abstract
Fibers formed of a blend of metal oxide, such as titanium or zirconium oxide, with etheric phosphazene are formed by preparing solutions of etheric phosphazene and inorganic alkoxides, such as titanium isopropoxide. The solutions are then formed into fibers and cured at room temperature or with moderate heating. Fibers produced can be extensible, tough, hard, flexible, or brittle. They are multicomponent blends of the titaninum or zirconium oxide and phosphazene. The composite may be doped with low lattice energy salts to form conductive fibers.
