Annotation Cílem diplomové práce je studium beta-nukleace povrchově modifikovaných oxidů železa v izotaktickém polypropylenu. Nanočástice Fe3O4 a částečně zoxidovaného Fe3O4 byly použity jako plnivo, které bylo dvěma způsoby modifikováno surfaktantem a beta nukleačním činidlem; a to precipitační a dvou stupňovou cestou. Účinnost beta nukleačního činidla na povrchu nanočástic byla studována pomocí širokoúhlého rozptylu záření X (WAXD) and DSC. Modifikace nanočástic byla studována pomocí infračervené (FTIR) a dielektrické spektroskopie stejně jako testování magnetických vlastností. Tato práce se zabývá relativním obsahem beta krystalické fáze a krystalizační teplotou iso-propylenu plněného zoxidovanými částicemi Fe3O4 modifikovanými precipitační a dvou stupňovou cestou. Nanočástice oxidů železa modifikované dvou stupňovou cestou vykazují lepší nukleační účinek. Nicméně obě uvedené způsoby modifikace mohou vést do určité míry k reakci modifikátorů s nanočásticemi.
Annotation in English The aim of this Master thesis is to study of beta-nucleation of surface modified iron oxides in isotactic polypropylene. Fe3O4 and partly oxidized Fe3O4 nanoparticle were utilized as filler which was modified with surfactant and beta-nucleating agent by precipitation method and two-step method. The efficiency of beta-nucleating agent modified on the surface of nanoparticle was studied by WAXD and DSC. The modification of nanoparticle was studied by FTIR spectrometry, dielectric testing and magnetic testing. This work deals with the relative beta-crystal content and crystallization temperature of iso-polypropylene filled with oxidized Fe3O4 nanoparticle modified by precipitation and two-step method. Iron oxide nanoparticles modified by two step method show better nucleation effect. However, the modifiers may to some extent react with nanoparticles in both methods.
