Inkjet-Printed Gold Electrodes on Paper: Characterization and Functionalization

Gold nanoparticles were synthesized and inkjet-printed on a paper substrate and IR-sintered to produce conductive electrodes. The electrodes were further functionalised by using self-assembled octadecanethiol monolayers (SAMs). The effect of sintering, print quality, and SAM formation were examined by topographical, chemical and electrical methods. With optimised printing parameters, a volume resistivity of ∼1.6 ×10–7 Ω m was attained by a single print layer.
