A robust, gravure-printed, silver nanowire/metal oxide hybrid electrode for high-throughput patterned transparent conductors
Ag NWs dispersed in ethanol were purchased from Blue Nano Inc. Glass substrates (1 mm thick) were obtained from VWR Scientific. Planarized polyethylene naphthalate substrates (PEN) were provided by Dupont Teijin Films. All solvents and sol-gel precursors were obtained from Sigma Aldrich. 
IZO/Ag NW composite inks were prepared from a mixture of Ag NWs dispersed in ethanol and IZO sol-gel precursors (Indium Acetate, 99.99%, Zinc Acetate dehydrate, 99.99%) dissolved in a 2:1 mixture (volume ratio) of 2-methoxyethanol and monoethanolamine. The sol-gel precursor ink was sonicated for 1 hour until complete dissolution occurred, and the solution was subsequently filtered through a 0.2 μm PTFE filter before mixing with the Ag NW dispersion. During storage in a dry environment, the ink remained stably dispersed for more than one month.
