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 K-3[Fe(CN)(6)] and AgNO3 solutions. In the second step, silver hexacyanoferrate(III) was reacted with anilineHNO(3) solution. Silver hexacyanoferrate(III) acted as an oxidant to polymerize aniline monomer. Silver hexacyanoferrate(II)/conducting polyaniline composite was prepared at different temperatures (37 degrees C, 27 degrees C, 17 degrees C) and in different concentrations of AgNO3 (0.4M, 0.8M, 1.2M) and HNO3 (1M 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.
