Abstract :
The composite materials on the basis of NiFe2O4 nanoparticles and polyethylene matrix have been synthesized. The concentration dependences of volume resistivity εV, permittivity ε, saturation magnetization σS and reflection and attenuation factors have been investigated. It has been determined that percolation threshold in these materials had been located at the concentration interval 20...30 of weight %. It has been shown that the composites on the basis of NiFe2O4 nanoparticles and polyethylene matrix might be used as the components of gradient radio absorbing coatings.
