Electrochemical and spectroscopic characterization of AgNP suspension stability influenced by strong inorganic acids

Silver nanoparticles are of utmost importance as functional material for inkjet printed electronics. Typically, to formulate inkjet- printable conductive ink, silver nanoparticles are synthesized, precipitated and dried, before being redispersed in an appropriate solvent mixture. For the precipitation step, usually relatively large quantities of organic solvents are required. In this work, we have studied the application of mineral acids, i.e. perchloric, sulfuric and phosphoric acids, as effective nanoparticle precipitants. The synthesized poly(acrylic acid) stabilized powdered product was characterized with FTIR, while the stabilities of the prepared dispersions were characterized by a novel approach via cyclic voltammetry, along with UV/Vis spectrophotometry. All of the investigated acids have shown to be promising candidates as precipitation agents. However, 0.01 M perchloric acid has shown a minimal effect on the surface stabilizer of the silver nanoparticles, thereby enabling highly effective conductive ink formulation with as- precipitated nanosilver.
