The features of the structure and chemical composition of coatings deposited from the volatile products of electron beam dispersion of a mechanical mixture of PTFE, iron nitrate, and aluminum are determined. It is shown that under such conditions of generation of the gas phase, coatings are formed consisting of a polymer matrix and containing particles of oxide, a free metal, and a certain amount of the initial undecomposed salt. The result of exothermic reactions in the crucible is partial defluorination and increased defectiveness of the molecular structure of the fluoroplastic matrix. It is noted that the morphology of the composite layer in comparison with the morphology of PTFE is more “loose” and porous, containing a significant number of dispersed formations that form larger structures. The composite coating is heterogeneous in terms of chemical composition and during its annealing, continuity is violated.
Keywords: iron nitrate, polytetrafluoroethylene, exothermic reactions, electron beam dispersion, molecular structure, morphology.
