Polyacrylonitrile molecular weight effect on the structural and magnetic properties of metal–carbon nanomaterial

The influence of the molecular-weight parameters of the polymer on the functional properties of metal–carbon nano-materials (MCN) was revealed for the first time. A difference in the phase composition of iron-containing nanoparticles was established employing high and low molecular weight poly-acrylonitrile, which determines the magnetic characteristics of the MCN.
