Description
Summary:Copper-containing nanoparticles synthesized in high-pressure polyethylene matrix by the method of thermal decomposition of (CH/sub 3/COO)/sub 2/Cu/spl middot/H/sub 2/O are presented. Average dimensions of nanoparticles and size distribution were determined by transmission electron microscopy and X-ray phase analysis. It was shown that, with increasing copper concentration, the nanoparticles increase in size from 6 to 18 nm. The structure of copper-containing nanoparticles was determined by the method of EXAFS spectroscopy in fluorescence mode and in transmission one. It was shown that the samples containing 3 wt% and 5 wt% of copper are most likely to include CuO particles with tenorite structure. When the copper concentration is increased to 10 wt%, the nanoparticles contain Cu/sub 2/O and metallic copper phases. An increase in copper concentration to 40 wt% results in complication of the composition and the structure of the particles.
