Влияние наночастиц оксида железа Fе3O4 на структуру и теплофизические свойства нанокомпозитов на основе полиэтилена высокой плотности

Abstract

HDPE/Fe3O4 composites with Fe3O4 nanofiller content ω = 1, 3 and 5 vol. %. The structure and thermophysical properties of HDPE/Fe3O4 nanocomposites were studied and it was found that with an increase in the concentration of Fe3O4 nanoparticles in the polymer matrix, cardinal morphological changes occur in the supramolecular structure of the HDPE matrix. It has been established that with an increase in the concentration of the nanofiller, the mobility of the macromolecular chains of the matrix and the thickness of the crystalline lamellae decrease. Nanoparticles disrupt the regularity of lamellae in the crystalline phase of the polymer matrix, and in the amorphous region they prevent the formation and growth of new crystalline domains.
