Resumo

Molybdenum-containing composite nanomaterials are synthesized by the thermal decomposition
of molybdenum hexacarbonyl in a solution-melt of polyethylene in mineral oil. The concentration of a metalcontaining
filler in the composite materials varied from 1 to 20 wt %. A technique for preparing film samples
for spectroscopic studies is developed, and the samples obtained are studied by UVI, IR, and Raman spectroscopy.
It is found that additional absorption bands appear in the IR range, whose intensity depends on the
concentration of molybdenum-containing nanoparticles in the composite materials. The spectral characteristics
of Raman scattering show that all samples are characterized by the stretching of the C–C bond. In the
visible light region, the spectrum of nanocomposites has a flat edge of its own absorption located in the region
of wave numbers (18–31) × 103 cm–1.
