The preparation of composites between polyaniline-silver (PANI-Ag) via interfacial polymerization

Abstract In this study, polyaniline-silver (PANI-Ag) composites between aniline monomer and Ag particles in silver nitrate were prepared via interfacial polymerization method at room temperature. The objective was to study the effects of mass ratios of aniline monomer to Ag particles in silver nitrate (1:0.5, 1:1, 1:1.5, 1:2 and 1:2.5) on the electrochemical properties. The characterization techniques included FTIR, XRD, SEM and EDAX. FTIR and XRD results presented the success of the synthesis of the composites and crystallization of the PANI-Ag composites due to the presence of silver. SEM and EDAX techniques indicated that polyaniline nanofibers were successfully covered on the Ag particles. The CV results showed the higher specific capacitance with increasing amounts of Ag particles.
