Abstract
Iron-containing composites with nanoparticles are synthesized by the method of thermal decomposition of pentacarbonyl and iron formate in a polyethylene melt. The synthesized nanoparticles are characterized by transmission electron microscopy (TEM), X-ray phase analysis, and Mössbauer spectroscopy. The size of nanoparticles synthesized from iron pentacarbonyl and iron formate is 5.3 and 11.5 nm, respectively. It follows from the diffraction patterns that the particles have a complex composition. Composite materials are obtained based on iron nanoparticles and high-density polyethylene (HDPE). According to dynamic mechanical analysis, the elastic modulus of HDPE filled with particles obtained from iron pentacarbonyl is higher than for matrices containing iron formate. The biocidity test showed that the particle-modified matrix inhibits the growth of microorganisms more effectively than pure polyethylene.
