Development of high concentrated aqueous silver nanofluid and inkjet printing on ceramic substrates

Abstract

In this paper, the formulation of a high Ag loading (45 wt %) aqueous ink and its subsequent printing on three different ceramic substrates were reported. Monodispersed Ag nanoparticles with a size down to 10 nm were successfully synthesized in aqueous medium. These nanoparticles were then successfully dispersed up to 45 wt% in aqueous medium with the aid of a co-polymer, Pluronic F127. The printed tracks show the electrical conductivity of 3μΩcm close to the value of silver bulk (1.6 μΩcm). The use of high solid loading inks reduces the number of printed layers required for thick, dense and conductive film thus leading to the reduction of the costs, and high efficiency of the printing process. High solid loading also results in the finer printed features. The effect of substrates, printing temperature and dot spacing on the size and morphology of printed silver features was investigated. Increasing the dot spacing together with the substrates temperature resulted in the limited ink spreading, hence narrow printed line and improved geometry of printed patterns.

Screen Printing of Highly Loaded Silver Inks on Plastic Substrates Using Silicon Stencils

“…Kosmala et al 19 reported inkjet printing of silver ink with a solid loading up to 45 wt % to achieve thick conductive lines for low resistance. Ahn et al 20 used highly concentrated (>70 wt %) silver ink for a direct ink writing method for omnidirectional (3D) printing of fine and high aspect ratio silver lines.…”

Circuit patterns printed on paper have obvious advantages such as low cost, portability, environmental protection and recyclability.…”

Zirconia nano-colloids transfer from continuous hydrothermal synthesis to inkjet printing

“…The formulation of aqueous inks with suspended nanoparticles has already been successfully demonstrated for Ag colloids [17,18]. In particular, stable inks with a solid loading up to 45 % wt of Ag nanoparticles were prepared with the aid of a polyethilenoxide-polypropilenoxide copolymer [17].…”

In particular, stable inks with a solid loading up to 45 % wt of Ag nanoparticles were prepared with the aid of a polyethilenoxide-polypropilenoxide copolymer [17]. On the other hand, inkjet printing of several metal oxide nanoparticles (Al2O3, TiO2, WO3) was reported to be more challenging [19][20][21][22][23].…”
