Composite materials containing nanoscalar particles, process for producing them and their use for optical components

Abstract

Composite materials that contain nanoscaled particles are produced in that a) a compound, which is soluble in the solvent and belongs to a metal of the groups 6 to 15 of the periodic system or lanthanides, is reacted in an organic solvent with b) a precipitating reagent in order to form antimonides, arsenides, chalcogenides, halogenides or phosphides of the metal of the metal compound (a) in the present of c) a bifunctional compound, which exhibits at least one electron pair-donor group and at least one group, which can be converted through polymerization or polycondensation into an organic or inorganic network; the resulting stabilized sol of nanoscaled particles is mixed with d) a compound, which can be polymerized or cured thermally or photochemically into a polymer, and e) a polymerization initiator; a hydrolysis and polycondensation of the optionally present groups that can be converted into an inorganic network is conducted; and the material is cured thermally of photochemically. The nanocomposites according to the invention are especially suitable for optical elements.
