- Аннотация: It is shown for the first time that the infrared heating of polydiphenylamine in the presence of cobalt (II) acetate Co(CH3CO2)2 · 4H2O in an inert atmosphere at a sample temperature of T = 250−600°C leads to the formation of a metal-polymer nanocomposite in which Co nanoparticles are dispersed in a polymer matrix at the expense of condensation of diphenylamine crystalline oligomers with hydrogen release, promoting the reduction of Co2+ to Co0. The formation of Co nanoparticles is confirmed by X-ray phase analysis. According to data from transmission electron microscopy, Co nanoparticles have sizes of 2 < d < 8 nm. The investigation into the magnetic and thermal properties of Co/polydiphenylamine nanocomposite has shown that the nanocomposite obtained is superparamegnetic and thermostable.
