Patent

CA 2721106

The invention relates to metal or metalloid oxide nanoparticles with a mean particle size of 2 to 250 nm, characte-rised in that the nanoparticles have at least two different radically polymerisable groups on the surface. The invention further rela-tes to nanocomposites made from said nanoparticles and methods for production thereof. (57) Zusammenfassung: Gegenstand der Erfindung sind Metall- oder Halbmetalloxidnanopartikel mit einer mittleren Teilchen-- groBe von 2 bis 250 nm, dadurch gekennzeichnet, dass die Nanopartikel wenigstens zwei verschiedenartige, radikalisch polymeri-- sierbare Gruppen auf der Oberflache aufweisen. Die Erfindung betrifft ferner aus solchen Nanopartikeln hergestellte Nanokompo - site sowie Verfahren zu deren Herstellung.

L'invention concerne des nanoparticules à base d'oxydes métalliques ou d'oxydes semimétalliques présentant une taille moyenne de particules comprise entre 2 et 250 nm. L'invention se caractérise en ce que ces nanoparticules présentent sur leur surface au moins deux groupes polymérisables par voie radicalaire de type différent. L'invention concerne en outre des nanocomposites préparés à partir de ces nanoparticules, ainsi que leurs procédés de préparation.
