Printing and encapsulation of electrical conductors on polylactic acid (PLA) for sensing applications

Inkjet and microcontact printing of functional materials on foil for the fabrication of pixel-like capacitive vapor microsensors

“…Silver was used for interconnections instead of gold due to its ease of processing and cost effectiveness. After a mild thermal sintering of the silver ink in the oven, or alternatively under a near-infrared lamp [47], we confirmed that it was electrically conductive and that the junction Au/Ag was conductive as well.

Roll-to-roll infrared (IR) drying and sintering of an inkjet-printed silver nanoparticle ink within 1 second

“…33 Surprisingly, only a few studies are available about sintering of printed Ag layers using IR radiation. [34][35][36][37][38] Denneulin et al 34 reported about IR sintering of silver layers on paper substrates with a sheet resistance of 1.9 O & À1 after 2 min of IR exposure. Tobjo ¨rk et al 35 also used paper substrates and demonstrated conductivity values of up to 20% of bulk Ag after only 15 s of post-processing time with the IR system.…”

Polylactic acid as a biodegradable material for all-solution-processed organic electronic devices

“…Surprisingly enough, in the scientific literature lamination of copper foils [21]. Vásquez Quintero et al 113 proved that it is possible to fabricate conductive patterns 114 on the top of PLA substrates by means of printing tech-115 niques [22]; in this case, ink curing was performed by 116 using near infrared (NIR) photonic curing, in order to avoid 117 thermal damages to the PLA substrate. PLA has also been 118 used as a substrate for the fabrication of clean-room 119 processed either organic [23] or, more recently, inorganic 120 transistors [24].…”
