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.
