Dielectric Properties of Ethylene Vinyl Acetate Copolymer Composites Filled with Carbon Nanotubes, Graphene Nanoplatelets and Iron Oxide Nanoparticles

Abstract:

Ethylene vinyl-acetate copolymer (EVA) composite materials containing multiwall carbon nanotubes (MWCNT), graphene (Gr) and iron (III, IV) oxide (Fe₃O₄) nanoparticles where processed by melt blending. Film specimens were prepared by using compression moulding method. All nanoparticles content in samples was chosen equal to 20 wt.%. The material dielectric spectroscopy was used in a range of 10^-2 Hz to 10⁷ Hz to investigate nanoparticle effect on the dielectric active (ε’) and passive components (ε’’), specific electrical conductivity (σ’) and dielectric loss (tg) for the characterization of the dissipation of electromagnetic energy.
