Synthesis and properties of rhenium–polyethylene nanocomposite

New rhenium-containing composites were synthesized by thermodestruction of different rhenium complexes. The composites consist of rhenium-containing nanoparticles stabilized by low-density polyethylene matrix. The structure of composites was characterized by means of TEM, EDS, XRD, EXAFS and EMR. Transmission electron microscope images illustrate that the rhenium-containing nanoparticles are 15.0 ± 0.3 nm in size. The particles consist of Re, Re2O7, ReO3 and ReO2. In the electrophysical measurements it was found that permittivity and attenuation of microwave radiation correlate with composition of rhenium-containing nanoparticles.
