Abstract:

In this study, silver nanoparticles were synthesized with a starch-based reduction biosystem at room temperature. With this approach, high concentration silver nanoparticles were produced on a large scale with a low starch/AgNO3 mass ratio, which was very advantageous for the low cost and high conductivity. Conductive inks were prepared from the synthesized silver nanoparticles by dispersion of the nanoparticles in a non-conductive commercial ink. Various patterns have been developed by printing silver nanoparticles with different percentages from 5% to 25% on a cotton substrate using a syringe. The printed patterns show a resistivity drop depending on the sintering temperature and nanoparticle concentration in the range of 8M and 8× 10-5 MΩ by heat treatment varying between 60°C and 320°C for 10min. In addition, a LED test was successfully performed on the fabrics. These flexible patterns produced by inkjet printing would present a considerable success for textile-based electronic devices at a low cost. Recent Publications 1.
