Polyaniline-cobalt coordination polymer (abbreviated as PANI-Co) was synthesized using peroxydisulphate as an oxidant in the solution containing 0.1 mol dm(-3) aniline, 0.5 mol dm(-3) HCl and an adequate content Of CoCl2 center dot 6H(2)O at room temperature. The conductivity of PANI-Co was 0.5 S cm(-1). The cyclic voltammogram results indicated that the PANI-Co film was of electrochemical activity. and the EPR spectrum showed that there were unpaired electrons in the PANI-Co. The relationship between magnetization (M) and the applied magnetic field (H) suggests that PANI-Co was soft ferromagnetic material at room temperature. Thus, the PANI-Co was both conductive and ferromagnetic. Moreover, UV-vis and FTIR spectra showed that there existed a strong interaction between Co2+ and PANI chains. (C) 2009 Elsevier B.V.
