The need to produce conductive and smart fabrics with inkjet printers is one of the challenges of today. In this study, an ink was created that creates an electrically conductive layer on cotton fabric after printing. To create the aforementioned layer, first a chemical reduction process is performed using an inkjet printer, and the electrical conductivity is created by the printed layer. For this purpose, in the first stage, a silver nitrate-based ink was formulated, and to increase the electrical conductivity of the printed layer, biodegradable carboxylic acids with different functional groups were used to increase the crosslinking process of cotton fabric. After treating the prepared fabrics and printing with silver nitrate and sodium hypophosphite-based ink, the electrical resistance of the printed layer and the effect of the number of functional groups on it were investigated. Also, the thermal properties, visible/ultraviolet spectroscopy, and infrared analysis of the prepared ink and the morphology of the printed nanoparticles were investigated. The results showed that the surface tension of the synthesized ink was 38.6±1.37 mN/m. The best sample was butane tetracarboxylic acid, which showed a wrinkle reversibility angle of 157 degrees and a decrease in tensile and force at break point values of 11.38 and 12.48 %, respectively. The lowest electrical resistance was also found in this sample, which was 0.10 megaohm after 5 printings. https://pccc.icrc.ac.ir/article_82141_08b872a53d2591b8d36271230db6ef76.pdf
