The structure and dielectric properties of the nanocompositewere investigated. The dispersion of the magnetite nanopartcles in polymer matrix was studied by scanning electron microscope(SEM, Carl Zeiss). The dielectric properties of composite materials were examined by means of E7-21 impedancespectrometre in the frequency range of 10(2) Hs -10(6)Hs and over the temperature range of298 degrees-433 degrees K.

Abstract
The structure and dielectric properties of the nanocompositewere investigated. The dispersion of the magnetite nanopartcles in polymer matrix was studied by scanning electron microscope(SEM, Carl Zeiss). The dielectric properties of composite materials were examined by means of E7-21 impedancespectrometre in the frequency range of 10(2) Hs -10(6)Hs and over the temperature range of298 degrees-433 degrees K. It was shown that the introduction of magnetite (Fe3O4) nanoparticles into the polypropylene matrix increases the dielectric permittivity of nanocomposites. It was found that the decrease in the resistivity up to 318 K is associated with increasing ionic conductivity of the nanocomposite.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
