Title: Postopek priprave magnetnih nanokompozitov z visoko vsebnostjo nanodelcev dispergiranih v polimerni matrici [SL], Procedure of Preparation of Magnetic Nanocomposites with High Content of Nanoparticles Dispersed in Polymer Matrix [EN]
Description: The subject of invention is a procedure of preparation of a magnetic nanocomposite which contains a high content of dispersed nanoparticles within a polymethyl metacrylate matrix. Magnetic nanocomposites are applied on various fields of electrical engineering, for example as absorbers of high frequency electromagnetic waves. The procedure is based on the preparation of a concentrated colloidal suspension of previously synthesised magnetic nanoparticles in a nonpolar carrier liquid. A monomer and suitable initiator are dissolved in the carrier liquid of this suspension. A polymer in which magnetic nanoparticles are dispersed is isolated during the precipitation polymerisation. The content of nanoparticles is controlled by the ratio between the content of dissolved monomer and the content of suspended nanoparticles.
