The electronic structure and geometry of metal−carbon nanocomposites based on the pyrolyzed poliacrylonitril (PPAN) with Cu, Si, Fe, Co, Ni atoms using the DFT method have been theoretically studied. The effect of nitrogen on the stability of PPAN and its conductivity has been determined. The electrophysical properties and structure of metal nanocomposites have been studied using the XFA method. The composites have been produced by IR heating. We suggest that metal−carbon nanocomposites form due to the special processing of the (PAN−MeR) samples. Metal nanoparticles are regularly dispersed in the nanocristalline matrix of PPAN. The conductivity of this metal−carbon nanocomposites has an activation character and varies from10 −1 to 10 3 Om/sm depending on synthesis temperature (T = 600-900 °С). The results of theoretical and experimental research are in good agreement.
