Thermophysical properties of fluoropolymer composites with cobalt nanoparticles

The thermophysical properties of molecular composites based on polytetrafluoroethylene and cobalt nanoparticles as a function of the temperature and concentration of the CoFP modifier (cobalt-organofluorine powder) are studied. The studies demonstrate a correlation of the heat capacity and the concentration of the CoFP modifier with previously conducted studies of thermal conductivity and thermal diffusivity. Furthermore, the anomaly of the thermophysical properties of a fluoropolymer nanocomposite at low concentrations of nanoparticles is noted, which does not correspond to the additivity rule, this being explained by the transition of the polymer system from single-phase to multiphase.
