“…In subsequent experiments, many researchers have attempted to perform RIJ procedures using AgNO 3 , silver ammonia ([AgNH 3 ] + + OH À ) and silver neodecanoate as Ag precursors as well as ascorbic acid, formaldehyde, hydroquinone or diethanolamine. 20,[107][108][109][110] Kao et al reported on the reduction of AgNO 3 with formaldehyde via the silver mirror reaction. 107,108 Aer performing the reaction on glass substrates and washing the patterns with nitric acid, a conductivity of 6% compared to bulk Ag has been obtained at room temperature.…”

“…This approach was later on improved by the addition of PVP to the formaldehyde solution in order to gain more control over the reaction and, hence, to obtain equally sized and shaped NPs. 108 The resulting material is equal to an NP based ink aer drying. Removal of the PVP was achieved by washing with ammonia, reaching 10% of bulk Ag conductivity at room temperature.…”

Well-defined high resolution structures with excellent electrical conductivities are key components of almost every electronic device. Producing these by printing metal based conductive inks on polymer foils represents an important step forward towards the manufacturing of plastic electronic products on an industrial scale. The development of fast, efficient and inexpensive post-deposition sintering technologies for these materials is an important processing step to make this approach commercially viable. This review discusses the advances in alternative sintering approaches for conductive, metal containing inks, which can be processed by inkjet-printing processes. Each sintering approach is examined regarding its mechanism, its compatibility with commonly used materials in the field of flexible electronics, its compatibility with high-throughput manufacturing processes and its applicability to the production of flexible electronic devices.

“…In 2007, Bidoki et al 47 printed ascorbic acid and silver nitrate solution sequentially on papers to produce several antenna and capacitor patterns. Kao et al 24,48 printed aqueous silver ammonium and formaldehyde solutions through two different nozzles to perform the silver mirror reaction. Silver can quickly recover in the printed area within seconds to form highly conductive thin film features on plastic surfaces.…”

This review briefly summarizes the recent development in fabrication of conductive tracks with inkjet printing technology. Special emphasis will be placed on material selection and printing procedures. Troubleshooting guidelines for frequent problems in inkjet printing methods, such as material selection, ink formulation, ink-substrate interaction, and post-treatment of inks, are elucidated in this article to fabricate conductive tracks or electrodes with well-defined patterns. Related applications and unsolved challenges are also briefly reviewed in this article.

“…However, the organic salt formulation processes are usually quite complicated and require several synthetic steps. On the other hand, in the literature, silver nanoparticles or thin films are generally synthesized from redox reactions of silver ions and reducing agents, such as ethylene glycol, polymers [such as poly(vinylpyrrolidine) (PVP)], − or amines, at temperatures ranging from 60 to 100 °C. If silver ions and the reducing agents can coexist in a solution for a long time at room temperature before printing, the as-printed ink can then be heated and generates silver nanoparticles on the printed area to form silver patterns at temperatures below 100 °C.…”

In this study, a simple and effective silver ink formulation was developed to generate silver tracks with high electrical conductivity on flexible substrates at low sintering temperatures. Diethanolamine (DEA), a self-oxidizing compound at moderate temperatures, was mixed with a silver ammonia solution to form a clear and stable solution. After inkjet-printed or pen-written on plastic sheets, DEA in the silver ink decomposes at temperatures higher than 50 °C and generates formaldehyde, which reacts spontaneously with silver ammonia ions to form silver thin films. The electrical conductivity of the inkjet-printed silver films can be 26% of the bulk silver after heating at 75 °C for 20 min and show great adhesion on plastic sheets.
