  • PRECIPITATING NANOPARTICLES IN MONOMERS FOR PRODUCING HYBRID PARTICLES
    Publication number: 20150225532
    Abstract: The present invention relates to a process for producing hybrid nanoparticles comprising at least one inorganic material and at least one polymeric organic material, comprising at least the steps of (A) providing an emulsion comprising a disperse phase (I) comprising at least one pre-cursor compound of the at least one polymeric organic material and at least one compound which brings about the precipitation of the at least one inorganic material, a continuous aqueous phase (II), and optionally at least one compound which brings about the polymerization of the at least one precursor compound, this being present in the disperse phase (I), in the continuous aqueous phase (II) or in both phases (I) and (II), (B) adding at least one precursor compound of the at least one inorganic material to the emulsion from step (A), so as to form the at least one inorganic material by precipitation in the disperse phase, (C) optionally adding at least one compound which brings about the polymerization of the at least one precu
