Abstract: Silver hexacyanoferrate(II)/conducting polyaniline composite was synthesized in two steps process; In the first step, silver hexacyanoferrate(III) was synthesized by reaction of K3[Fe(CN)6] and AgNO3, solutions. In the second step, silver hexacyanoferrate(III) was reacted with aniline/HNO3 solution. Silver hexacyanoferrate(III) acted as an oxidant to polymerize aniline monomer. Silver hexacyanoferrate(II)/conducting polyaniline composite was prepared at different temperatures (37 °C, 27 °C, 17 °C) and in different concentrations of AgNO3 (0.4M, 0.8M, 1.2M) and HNO3 (IM and 2M). Silver hexacyanoferrate(II)/conducting polyaniline composite was characterized by FTIR and DC conductivity was measured by four probe technique. Conductivity of Silver hexacyanoferrate(II)/polyaniline composite was found to be increased with increasing temperature. However, conductivity decreased significantly with increasing concentrations of AgNO3, but remained unaffected with the change in HNO3 concentration from 1-2 molar.
