Аннотация: Electrical transport properties of a composite material based on ultrahigh molecular weight polyethylene having NiO nanoparticles deposited on its granules have been investigated using impedance spectroscopy. This has made it possible to study electrical engineering properties of an ensemble of nanoparticles uniformly distributed oПоказать полностьюver a polymer matrix. We have evaluated the dielectric permittivity, capacitance, and dielectric loss tangent of the composite and found frequency dependences of the real and imaginary parts of its complex conductivity. The hopping conduction mechanism has been shown to prevail in the composite at frequencies of up to 1 MHz, giving way to a relaxation mechanism at higher frequencies. We discuss a correlation between structural features of the composite and charge transport processes.
