In this work, gold powder made from gold leaf investigated to have the potential as a filler of conductive ink. The resistance of a conductive film decreased from 6.2kΩ to 1 Ω by adding only 2.0wt% of gold powder to conductive polymer (PEDOT:PSS) ink. The change of the resistance depends on the characteristics of gold powder. Gold powder with smaller and uniform sizes and good dispersibility is beneficial to form a continuous percolation network.
