Abstract

Previous experiment on silver ink formulation for inkjet printing deposition on paper substrate determined the importance of scouting good ink compositions to yield conductive printed films for electronic applications. Three film samples A, B, and C were prepared in this study from synthesized inks namely: Ink A or silver ink, an aqueous solution of silver nitrate with dimethylamine as sensitizing agent; Ink B or formaldehyde ink composed mainly of formaldehyde as the reducing agent for the silver salt; and Ink C or silver / PAni - EB dispersion ink which contained a 50;50 mixture of ink A and PAni - EB dispersion ink C yielded deposited film with the lowest sheet resistivity value of 0.33 compared to other samples. Sheet resistivity values were confirmed by the evaluation of percent transmittance (% T) of strong N=O hands at 1469.76 cm-1 absorption frequency from the FTIR - ATR results of the deposited films. PAni -EB thus best performed as a reducing agent in ambient conditions in an ink formulation converting silver metals, and produced a film with the highest metal content, therefore the most conductive film
