Study of structure and properties of composites based on polytetrafluoroethylene and cobalt nanoparticles
This research presents the results of structure and properties studies of composites, based on PTFE and filler, which is a composite of cobalt nanoparticles and ultrafine PTFE. Composite materials were investigated by physico-chemical methods (TEM, SEM, XRD), determined the specific rate of energy absorption, heat stress and internal orientation, thermal properties measured permittivity. It is shown that obtained composites outperforms the original matrix of polytetrafluoroethylene. Magnetic investigations of the compositions confirm the presence of metal nanoparticles and their interaction with the polymer matrix.
