Polyaniline (PANI)‐silver complex was obtained from in situ reduction of hydrochloric acid‐doped PANI by the addition of sodium borohydride. The morphology and structure of the complex were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction. Four‐probe measurements and thermogravimetric analysis were employed to investigate electrical conductivity, thermal stability, and silver content. Conductivity of the PANI‐silver composite was up to 535.22 S cm −1 and silver content was 38.48 wt % as determined from the molar ratio of sodium borohydride to silver nitrate of 1.2 used during the synthesis. © 2013 Wiley Periodicals, Inc.
