Abstract
The present invention provides a surface coating of platinum in which the coating is formed from platinum in a black modification. This can be obtained by applying an organic platinum complex compound with platinum in the oxidation state 0 that decomposes thermally at temperatures below 200° C., or a coating composition which consists substantially of such a platinum complex compound, to the surface of a substrate and then thermally decomposing the platinum complex compound. The surface coatings can be used in many ways, for example as protective layers against mechanical and/or chemical and/or thermal effects, as antiadhesion layers, as antireflective layers or as catalytically active layers.
Claims21
A surface coating comprising a platinum coating that is formed from a black modification of platinum, said platinum coating comprising platinum and silicon and/or a silicon compound.
A surface coating of platinum in a black modification obtainable by:
- (a1) applying an organic platinum complex compound with platinum in the oxidation state 0 that decomposes thermally at temperatures below 200° C. with the formation of fine dispersoid platinum particles to the surface of a substrate;
- or
- (a2) applying a coating composition that consists substantially of a complex of platinum in the oxidation state 0 with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane to the surface of a substrate;
- and
- (b) thermally decomposing the platinum complex compound.
A process for preparing a surface coating of platinum in a black modification, comprising
- (a1) applying an organic platinum complex compound with platinum in the oxidation state 0 which decomposes thermally at temperatures below 200° C. to the surface of a substrate compound;
- or
- (a2) applying a coating composition that consists substantially of a complex of platinum in the oxidation state 0 with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane to the surface of a substrate;
- and subsequently thermally decomposing said platinum complex.
