Embodiment 1

[0128]In microemulsion polymerization, 5.8 g deionized water, 5.1 mM acrylic acid (from Sigma Aldrich), 0.125 mole methylmethacrylic acid MMA ( Sigma Aldrich) and 9.5 g of a 15% by weight SDS surfactant in water (from Fischer Chemical) were introduced into a 250 ml four-necked flask equipped with a reflux condenser. The reaction mixture was stirred at 120 rpm for 1 hour while heating in an oil bath at 85°C until a stable emulsion formed. 0.1 g of ethanolated iridium oxide sol (concentration 1 g / L) with an average particle size of 80 nm was added to the emulsion, and the mixture was stirred for an additional 2 hours. Then, an initiator solution containing 200 mg of potassium hydrogen peroxosulfate in 4 ml of water was slowly added over a period of 30 minutes. After 4 hours, the mixture was neutralized to pH 7 and the resulting miniemulsion of encapsulated iridium oxide particles was cooled to room temperature. The average particle size of the iridium oxide particles encapsula...

Embodiment 2

[0131] A miniemulsion was prepared as in Example 1 above. However, the amount of surfactant used was reduced to 0.25 g of 15% SDS in water to enlarge the resulting PMMA vesicles. The resulting PMMA-encapsulated iridium oxide particles had an average particle size of 400 nm. The emulsion was dried in vacuo for 72 hours and a suspension of the resulting encapsulated particles in ethanol was prepared at a concentration of 5 mg / ml.

[0132] According to the method described above in Example 1, a homogeneous sol was produced from 100 ml of a 20% by weight solution of magnesium acetate in ethanol, followed by the addition of 10 ml of 10% nitric acid at room temperature and stirring for 3 hours, followed by the addition of 4 ml of TEOS (obtained from Degussa ), and stirred at room temperature for another 2 hours at 20 rpm. Combine 2ml of the sol and 2ml of the suspension of encapsulated iridium oxide, stir at room temperature at 20rpm for 30 minutes, and then spray on metal substra...

Embodiment 3

[0134] In miniemulsion polymerization, 5.8 g deionized water, 5.1 mM acrylic acid (obtained from Sigma Aldrich ), 0.125mol of methylmethacrylate (metylmethacrylic acid) (also obtained from Sigma Aldrich) and 0.5g of an aqueous solution of 15% by weight SDS surfactant (obtained from Fischer Chemical), and in an oil bath at 85°C at 120rpm Stir for about 1 hour to obtain a stable emulsion. To this emulsion was added 0.1 g of ethanolated magnesium oxide sol (concentration 2 g / L) with an average particle size of 15 nm, and the mixture was further stirred for 2 hours. An initiator solution containing 200 mg of potassium hydrogen peroxosulfate in 4 ml of water was then slowly added over a period of 30 minutes. After 4 hours, the mixture was neutralized to pH 7 and the resulting fine emulsion of PMMA-encapsulated magnesium oxide particles was cooled to room temperature. The resulting emulsion had an average particle size of about 100 nm. The emulsion was dried in vacuo for 72 hours...

Abstract

The present invention relates to a process for the manufacture of metal containing materials or composite materials, the process comprising the steps of encapsulating at least one metal-based compound in a polymeric shell, thereby producing a polymer-encapsulated metal-based compound; and / or coating a polymeric particle with at least one metal-based compound; forming a sol from suitable hydrolytic or non-hydrolytic sol / gel forming components; combining the polymer-encapsulated metal-based compound and / or the coated polymeric particle with the sol, thereby producing a combination thereof; converting the combination into a solid metal containing material.

Description

technical field [0001] The present invention relates to a novel composition of matter and in particular to metal-containing composite materials made of organic and inorganic components. The present invention also relates to a method of producing a metal-containing material or composite comprising the step of encapsulating at least one metal-based compound in a polymer shell, thereby producing a polymer-encapsulated metal-based compound; and / or with at least A metal-based compound coating polymer particles; forming a sol from suitable hydrolyzed or non-hydrolyzable sol / gel forming components; combining the polymer-encapsulated metal-based compound and / or coated polymer particles with the sol , thereby producing its combination; the combination is transformed into a metal-containing solid material. Background technique [0002] Porous metal-based ceramic materials such as cermets are often used as components of friction-type bearings, filters, fumigators, energy absorbers or ...
