  • Patent number: 5010128
    Abstract: The invention provides a blend of metal oxide, such as silicon oxide, with etheric phosphazene. The invention optionally contains salt for antistatic coatings. The composition of the invention is formed by preparing solutions of etheric phosphazene and alkoxysilane, such as tetraethoxysilane. The solutions are then coated onto suitable substrates, or cast films and cured at room temperature or with moderate heating. The coatings and films produced are transparent, tough, hard, and flexible. They are multicomponent blends of the silicon oxide and phosphazene. It is also within the invention to form the blends with other metal oxides, rather than silicon, such as titanium, aluminum, or zirconium. The composite may be doped with low lattice energy salts to form antistatic composites.
