Abstract

A polymer layer comprising silicone contains oxide particles of SiO 2 , TiO 2 , Sb 2 O 3 , SnO 2 , Al 2 O 3 , ZnO, Fe 2 O 3 , Fe 3 O 4 , talc, hydroxyapatite or mixtures thereof and one or more metal traces embedded in the polymer layer, where the metal trace is bonded to the polymer silicon metal bond.

Claims (8)

1. A polymer comprising silicone containing oxide particles of SiO 2 , TiO 2 , Sb 2 O 3 , SnO 2 , Al 2 O 3 , ZnO, Fe 2 O 3 , Fe 3 O 4 , talc, hydroxyapatite or mixtures thereof and at least one metal trace embedded in said polymer, wherein the at least one metal trace is bonded to the polymer by a covalent silicon metal bond.

2. The polymer of claim 1 wherein said polymer comprising a silicone is an elastomer formulation, silicone copolymer, silicone-silicone copolymer, silicone-hydrocarbon copolymer, silicone block polymer, silicone block copolymer, silicone rubbers or mixtures thereof.

3. The polymer of claim 1 wherein said oxide particles are silica structures, silica foam, fumed silica, polycrystalline, fibers, fiber pieces or mixtures thereof.

4. The polymer as claimed in claim 1 wherein the particle size of said oxide particles are between 0.5 μm and 100 μm.

5. The polymer as claimed in claim 1 wherein the proportion of said oxide particles contained in said polymer is between 1 and 50 Vol.-%.

6. The polymer as claimed in claim 1 obtained by coating a first polymer layer containing said oxide particles and coating a second polymer layer on the first polymer layer having a lower Vol.-% to about 0 Vol.-% of said oxide particles.

7. The polymer of claim 1 comprising metal traces of one or more of the following metals titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, technetium, rhenium, iron, ruthenium, osmium, cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver, or gold, or an alloy of two or more metals, or a combination of two or more alloys or metal layers thereof.

8. The polymer of claim 1 comprising one or more of the following metals titanium, tantalum, chromium, iridium, palladium, platinum, silver, or gold, or an alloy of two or more metals, or a combination of two or more alloys or metal layers thereof.
