Printing Green Nanomaterials for Organic Electronics

Organic electronics have attracted increasing attention in recent years because of their large-scale production potential. In this context, inkjet printing as a scalable manufacturing process is well positioned for supporting the fabrication of organic electronics. In this paper, we propose a green substrate and functional inks based on bionanomaterials for fabricating dielectric and conductive layers using conventional inkjet technology. The feasibility of our approach is investigated by characterizing the properties of the conductive layers and capacitive structures and by demonstrating the functionality of a 1-D touch sensor. The printed conductive nanocarbon ink has a resistivity of 1.39 · 10

Ω · m, and the printed nanocellulose ink achieves a relative permittivity of 4.39. The proposed green nanomaterials and printing technique are promising for manufacturing organic electronic devices with reduced costs and environmental footprint.
