MICROWAVE ABSORPTION AND RADIATION PROTECTIVE PROPERTIES OF ULTRAHIGH MOLECULAR WEIGHT POLYETHYLENE FILLED WITH TUNGSTEN, CARBON BLACK, AND BORON NITRIDE
RÉSUMÉ
Electromagnetic wave and radiation protection properties of ultrahigh molecular weight polyethylene-based composite materials obtained by solid state mixing of powder components with subsequent hot pressing have been studied. Electromagnetic wave absorption increases with the carbon black content in samples; however, the presence of other fillers in the composite structure results in a decrease in the electromagnetic wave absorption. The attenuation coefficient of a neutron beam depends mainly on the boron nitride content, but the carbon black content affects the interaction of neutrons with the composite too. The measurements of γ-ray attenuation show that the composites investigated can attenuate effectively the fluxes with energies below ~0.2 MeV only. An increase in the tungsten content leads to an increase in the γ-ray photon attenuation coefficient, whereas an increase in the content of other fillers has no effect on the γ-ray protection properties of composites.
