Аннотация:The influence of the ligand on the formation of a system of conjugated-bonds at the initial steps of IR-pyrolysis of composites based on polyacrylonitrile and Co(C(5)H(7)O(2))(2) or CoCl(2) is demonstrated. An increase in IR-irradiation intensity leads to the formation of nanocomposites that contain nanoparticles of cobalt dispersed in a graphite-like matrix. Superparamagnetic Co particles are shown to make a significant contribution to the magnetic behavior of the nanocomposites prepared. The dependence of the electric properties of the composites on the synthesis conditions is investigated, and the role of Co nanoparticles in the growth of electrical conductivity is shown.
