ANOTACE

Nanokompozity polyamid 6 - montmorillonit Byla studována příprava nanokompozitů polyamid 6 - vrstevnatý silikát in situ polymerací. Jako plnivo byl použit nemodifikovaný montmorillonit a dále montmorillonit modifikovaný Ca2+ ionty, Mg2+ ionty a montmorillonit modifikovaný Ca2+ ionty a interkalovaný ε-kaprolaktamem. Modifikované silikáty byly charakterizovány TGA a WAXD analýzou. Nanokompozity polyamidu 6 byly připraveny aniontovou polymerací ε-kaprolaktamu v přítomnosti modifikovaných typů montmorillonitu. Vlastnosti takto připravených nanokompozitů byly studovány termickými metodami TGA a DSC. Stupeň exfoliace plniva byl vyhodnocen pomocí WAXD. Byly vyhodnoceny mechanické vlastnosti nanokompozitů.

ANNOTATION

Nanocomposites polyamide 6-montmorillonite The preparation of nanocomposites based on polyamide 6 and layered silicates was studied. As a filler inorganically modified montmorillonite was used. Homoionic montmorillonites Ca2+MMT and Mg2+MMT and montmorillonite modified with Ca2+ and intercalated with ε-caprolactam were prepared, and characterized by WAXD and TGA. Nanocomposites of polyamide 6 were synthesized by anionic polymerization of ε-caprolactam in the presence of modified fillers. Samples of polyamide 6 nanocomposites were further characterized by TGA and DSC. Morphology and level of interclalation/exfoliation were determined by WAXD. Mechanical properties were evaluated.
