Method for producing metal-containing nanoparticles enveloped with polymers and particles that can be obtained therefrom

摘要: The present invention provides a method to produce metal-containing nanoparticles enveloped with polymers, as well particles obtainable therefrom. In the according invention, at least one anionic polymerizable monomer is polymerized in presence of an macroinitiator room temperature. Subsequently, aliphatic or aromatic sulfide firstly added, followed by solution organosoluble metal salt aprotic organic solvent and finally homogeneous reducing agent. cation hereby reduced metal. Metal-containing are formed which covalently bonded growing polymerizates. salts preferably silver, copper, gold, tin, lead, chrome zinc, mixtures thereof. Anionic monomers comprise, way example, styrene (St), butadiene, isoprene, ethylene oxide, propylene caprolactone, lactide, glycolide, acrylates, methacrylates, bisacrylates, cyanoacrylates, amides, siloxanes, vinylpyridines acrylonitrile. suitable be used for antibacterial finishing polymers textiles materials. Furthermore, they production inks. If underlying metals those that show plasmon resonance, also applied sensors use resonance effect. accessible using do not aggregate agglomerate, their physical chemical properties remain unchanged over long period time.
