Abstract	Cilj ovog rada bila je sinteza nanočestica srebra metodom kemijske redukcije vodene otopine srebrovog (I) nitrata. Kao redukcijsko sredstvo korišten je hidrazin hidrat, dok je za stabilizaciju dobivenih nanočestica korištena poli(akrilna kiselina). Promatran je utjecaj perklorne, fosforne, sumporne i oksalne kiseline koncentracija 0,01 i 0,1 M na taloženje čestica i količinu adsorbiranog stabilizatora. Ispitivana je stabilnost dobivenih formulacija vodljivih tinti u Britton – Robinsonovim puferima u rasponu pH vrijednosti od 10,00 do 3,50. Nadalje, provedena je i elektrokemijska karakterizacija metodom cikličke voltametrije, i spektrofotometrijska karakterizacija UV-Vis spektroskopijom kako bi se odredile pKa vrijednosti poli(akrilne kiseline) adsorbirane na dobivene nanočestice.
Abstract (english)	The aim of this study was to synthesize silver nanoparticles by chemical reduction method of silver (I) nitrate. Hydrazine hydrate was used as a reducing agent and obtained nanoparticles were stabilized with poly(acrylic acid). The effect of 0,01 and 0,1 M perchloric, phosphorous, sulfuric and oxalic acid on particle deposition and amount of adsorbed stabilizer was studied. Furthermore, the stability of the resulting conductive ink formulations in Britton – Robinson buffers, ranged from pH 10,00 to 3,50, was tested. Electrochemical characterization by cyclic voltammetry and spectrophotometric characterization by UV-Vis spectroscopy was performed to determine the pKa values of poly(acrylic acid) adsorbed on the silver nanoparticles.
