Abstract

Polymer composites with nanoparticles localized on the surface of polytetrafluoroethylene microgranules
are synthesized by the method of thermal decomposition of metal-containing nickel salts. The synthesized
nanoparticles are characterized by transmission electron microscopy (TEM) and X-ray diffraction
analysis. The size of the nanoparticles ranged from 3.5 to 8 nm, depending on the precursor. It follows from
the data obtained that the particles have a complex composition. The study of magnetic properties shows that
the system of magnetic nickel-containing nanoparticles in the samples at room temperature is in a ferromagnetic
or superparamagnetic state. The blocking temperature and coercive force are calculated for each sample.

Keywords
