Abstract
Cilj rada je priprema i inkjet ispis vodljivih tinti dobivenih disperzijom amfifilnih nanočestica srebra u alkoholima. Amfifilne nanočestice srebra dobivene su u dva koraka. U prvom koraku sintetizirane su poli(akrilnom kiselinom) stabilizirane nanočestice srebra redukcijom srebrovog nitrata hidrazinom. U drugom koraku provedena je modifikacija tako dobivenih nanočestica srebra reakcijom amidacije. Pripremljene su 5 % - tne suspenzije nanočestica srebra u čistom etanolu i izopropanolu. Stabilnost suspenzija provjerena je mjerenjem zeta-potencijala. Veličina pripravljenih nanočestica određena je metodom dinamičkog raspršenja svjetlosti, te je bila u rasponu od 4 do 18 nm. Pripremljena je tinta u smjesi etanola i vode u omjeru 1:1, te smjesi izopropanola i vode u omjeru 1:1. Tintama je određena površinska napetost, viskoznost i gustoća, te su ispisane na PET podlogu. Ispisanim filmovima mjeren je površinski otpor.
Abstract (english)
The goal of this work is the preparation and inkjet printing of conductive inks prepared by dispersion of amphiphilic silver nanoparticles in alcohols. The synthesis of amphiphilic silver nanoparticles was performed in two steps. In the first step, silver nanoparticles were synthetized by a reduction of silver nitrate with hydrazine and poly(acrylic acid) as stabilizer. They were further modified via amidation reaction to make them amphiphilic. Silver nanoparticle suspensions (5 wt %) were prepared by dispersing the nanoparticles in ethanol and isopropyl alcohol. The stability of the suspensions was verified by measuring zeta potential. The size of the nanoparticles in the suspensions is in interval from 4 to 18 nm and was determined by using dynamic light scattering method. Finally, two inks were prepared, one in ethanol and water solution in equal volumetric ratios and second one in isopropyl alcohol and water solution in equal volumetric ratios (5 wt % nanoparticles). Surface tension, viscosity and density of the conductive inks were determined, and they were printed on PET substrate. The sheet resistance of the printed films was measured.
