Abstract
Metal oxide coated substrates are disclosed comprising a three dimensional substrate having a coating of metal oxide on at least a portion of all three dimensions thereof and having a polymeric inner core, produced by a unique process having particular applicability to the manufacture of tin oxide coated three dimensional substrates. Certain novel coated substrates, such as flakes, spheres and porous substrates are disclosed. The coated substrates are useful in polymers, catalysis, heating and shielding applications.
Claims30
An article comprising a multilayered three dimensional particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner polymer core, an inorganic oxide barrier layer associated with the external surface of said inner core and a thermally formed metal oxide coating associated with said inorganic oxide external surface layer, said inorganic oxide layer and said metal oxide coating being on at least a portion of said external and shielded surfaces.
An article comprising a multilayered three dimensional particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner polymer core, an inorganic oxide barrier layer associated with the external surface of said inner core and a metal oxide coating associated with said inorganic oxide external surface layer, said inorganic oxide layer and said metal oxide interactant coating being on at least a portion of said external and shielded surfaces.
An article comprising a multilayered three dimensional particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner thermoplastic polymer core, an inorganic oxide barrier layer associated with the external surface of said inner core and a thermally formed metal oxide coating associated with said inorganic external surface layer, said inorganic oxide layer and said metal oxide coating being on at least a portion of said external and shielded surfaces.
