Kind Code:
A3
Abstract:
PCT No. PCT/EP92/02327 Sec. 371 Date Jun. 28, 1994 Sec. 102(e) Date Jun. 28, 1994 PCT Filed Oct. 9, 1992 PCT Pub. No. WO93/07179 PCT Pub. Date Apr. 15, 1993.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.
