Abstract
Abstract A composite substance made of conjugated polymers that contain an inorganic moiety and an organic moiety in their molecule is provided. The conjugated polymers are produced from metal alkoxides and silane coupling agents, or else from metal alkoxides, silane coupling agents, and organic monomers. The conjugated polymers may be fired to give another composite substrate of this invention. These composite substances have both inorganic and organic characteristics, thereby attaining the excellent heat-stability, mechanical strength, resistance to chemicals, and workability.
