The composites of PANI and silver have been prepared at equimolar proportion of reactants. Seven acids, representing inorganic and organic acids, have been used to protonate PANI. The acids were selected with respect to their chemical indifference or the ability to precipitate or reduce silver(I) ions. The PANI-silver composites differed in the conductivity from 1.7 x 10-6 S cm-1 to 22.8 S cm-1 at comparable silver contents, 24 and 27 wt.% according to the used acid. The composites contained spherical silver nanoparticles of 40-80 nm in size and also macroscopic particles, irrespective of PANI entering the reaction.
