Abstract

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