Conductive polymers are widely used in manufacturing of electrodes of various technical application and for use in micro- and nanoelectronics. Also the application of conductive polymers for data storage and photoconversion is very challenging. The aim of the present work is investigation and optimization of the preparation technology for composites based on polyacrylonitrile (PAN). In particular we have prepared nanocomposites of iron (Fe/PAN) and nickel (Ni/PAN). The samples have been produced by means of the infrared heating method with various Fe and Ni concentrations. Structurual characterisation was performed by X-ray powder diffraction, X-ray fluorescence analysis, IR and Raman spectroscopy, as well as by synchrotron scattering and EXAFS techniques. It was observed that after synthesis the nickel atoms have formed crystallized nanoclusters with a size smaller than 30 nm. After analysis of the IR-spectra and literature data we can assume that the iron atoms are distributed within the the polymer matrix and most likey form iron polyacrylate (FePAcr). Finally the structure of nanocomosites is correlated to the magnetic properties of the obtained samples. Acknowledgement: M.Bulatov thanks DAAD for financial support.
