Direct ink-jet printing of silver nitrate–silver nanowire hybrid inks to fabricate silver conductive lines

Abstract

In this paper, silver nanowires were synthesized by a polyol method in the presence of PVP with Pt seeds. The silver nanowires were added to silver nitrate to form a binary hybrid ink to fabricate silver conductive lines by ink-jet printing on a flexible Kapton Ò substrate. The silver nanowires were used as an additive to the silver inks to lower the concentration of silver nitrate. The additive increased the ink's viscosity and promoted the conductivity of silver lines produced by ink-jet printing. Using a 20 wt% silver nitrate-silver nanowire ink, continuous and smooth silver conductive lines with a resistivity of 7.31 Â 10 À5 U cm could be fabricated by the ink-jet printing system.

Facile synthesis of high silver content MOD ink by using silver oxalate precursor for inkjet printing applications

“…In previous literature, the decrease in resistivity was obtained by increasing the silver content of the ink [10,18]. In this study, we propose a …”

“…The critical issue that needs to be addressed when inkjet printing is applied to these applications is ink development. Previously, conductive inks based on silver [6][7][8][9][10][11][12][13][14][15][16][17][18], copper [19], carbon [20], and conductive polymers [21] have been demonstrated, among which, silverbased ink has received great interests because of excellent conductivity and anti-oxidation properties of bulk silver. To date, two kinds of silver inks have been adopted for inkjet printing conductive patterns on substrates.…”

“…To date, two kinds of silver inks have been adopted for inkjet printing conductive patterns on substrates. In one approach, suspensions of silver nanoparticles were used [6][7][8][9][10][11]. Although silver nanoparticle inks are already commercially available and widely used, the approach has the problem of high annealing temperatures (generally N200°C), restricting its application on some flexible substrates (e.g., plastics) demanding for newly emerged electronics.…”

Síntese De Nanofios De Prata: Aplicações Em Tintas Condutoras

“…Tintas condutoras produzidas a partir de nanofios de prata são de interesse em diversas áreas, tais como displays, eletrônica, óptica e sensores, devido às vantagens de baixo custo de produção e fabricação. Tais tintas, demonstraram ter um grande potencial na indústria eletrônica [3]. Para a produção de tintas condutoras é necessário que haja a formação de nanocompósitos, neste caso, constituídos de fios de prata e polímeros.…”

Desenvolvimento de sensores eletroquímicos e colorimétricos para aplicações em amostras de interesse forense

“…O acoplamento de eletrodos ao substrato de papel, ocorre principalmente via técnicas de screen printed, silk screen ou ink jet printing [32,[38][39][40][41], onde os eletrodos são pintados dado um layout pré-estabelecido com tintas condutivas como carbono, prata e cobre, principalmente. Podem ainda ser confeccionados os eletrodos usando métodos mais sofisticados como a deposição metálica por sputtering [42,43].…”
