| 摘要 |
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 precursor compound of the at least one polymeric organic material if this has not been done in step (A), and (D) polymerizing the at least one precursor compound of the at least one polymeric organic material. The present invention additionally relates to nanoparticles producible by the process according to the invention, and to the use of inventive nanoparticles in optical, electronic, chemical, agro-chemical, medical, pharmaceutical and/or biotechnological systems or for the administration of at least one active ingredient. |

1. A process for producing hybrid nanoparticles comprising an inorganic material and a polymeric organic material, the process comprising:
adding at least one precursor compound (A) of the inorganic material to an emulsion comprising
a disperse phase (I) comprising a precursor compound (B) of the polymeric organic material and a first compound which brings about precipitation of the inorganic material,a continuous aqueous phase (II), and optionally a second compound which brings about polymerization of the precursor compound (B) and which is present in at least one of the disperse phase (I) and the continuous aqueous phase (II),so as to form the inorganic material by precipitation in the disperse phase (I),
optionally adding the second compound with the proviso that the emulsion does not comprise the second compound, and polymerizing the precursor compound (B). |
