摘要：

Novel graphite nanoplatelets/magnetite (GNP/Fe3O4)/epoxy composites with aligned under external magnetic field fillers and random fillers distribution have been developed. The influence of loading content of GNP nanoparticles and viscosity of composite medium on the alignment degree of fillers and electrical conductivity, shielding properties of GNP/Fe3O4/epoxy composites were considered. The results showed that Fe3O4 addition to the composite is reflected in increase in electrical conductivity by 3-5 orders of magnitude for the investigated composites with binary filler with random fillers distribution in comparison with composites with monofiller (GNP). Shielding properties of GNP/Fe3O4/epoxy composites were significantly improved due to increase in absorption.
