“…Additionally, roll-to-roll printing processes for the fabrication of organic devices have been proposed that could further lower their integration cost. [24] Overcoming the relatively poor life-time and the low carrier mobility of organic materials remains a major obstacle in the field. [25][26][27][28][29][30][31] There have been tremendous improvements in this regard through systematic studies and design of various organic molecules over the years, and still further optimization may be achieved in the future.…”

In recent years, there has been tremendous progress in the research and development of printable electronics on mechanically flexible substrates based on inorganic active components, which provide high performances and stable device operations at low cost. In this regard, various approaches have been developed for the direct transfer or printing of micro‐ and nanoscale, inorganic semiconductors on substrates. In this review article, we focus on the recent advancements in the large‐scale integration of single crystalline, inorganic‐nanowire (NW) arrays for electronic and sensor applications, specifically involving the contact printing of NWs at defined locations. We discuss the advantages, limitations, and the state‐of‐the‐art of this technology, and present an integration platform for future printable, heterogeneous‐sensor circuitry based on NW parallel arrays.

“…It is known that silver salts of primary and secondary fatty acid have very poor solubility in both water and common organic solvents [7,23,24]. Although silver salts of tertiary fatty acid have good solubility in organic solvents, the obtained solutions are light-sensitive [23][24][25]. Therefore, bis-benzylamino-silver(I) benzylcarbamate has some advantages.…”

A novel silver-containing compound bisbenzylamino-silver(I) benzylcarbamate with the molecular formula of C 22 H 26 N 3 O 2 Ag and structural formula of C 6 H 5 CH 2 NHCOOAg(NH 2 CH 2 C 6 H 5 ) 2 is synthesized by the reaction of benzylamonium benzylcarbamate and silver oxide. It crystallizes in triclinic crystal system and P-1 space group with a = 5.2006(5) Å , b = 14.6298(15) Å , c = 14.7246(15) Å , a = 68.729(2)°, b = 83.507(2)°, c = 85.412(2)°, and Z = 2. In the crystal, all of the silver atoms are two-coordinate, i.e., one silver atom symmetrically chelates with the two amino groups in two benzylamine molecules, while all the carboxylate groups only act as charge balancers. In addition, the crystal contains a large quantity of hydrogen bonds sustaining the stability of three-dimensional structure.

“…These processes need only one-step process to transfer pattern onto target surface, studied by Pudas et al, Lee et al, and Chun et al [3][4][5]. Owing to its high line resolution, the gravure offset printing technology may replace the current photolithography process and is considered as the advanced manufacturing technology for next generation electronic products [6].…”

Abstract:In order to engrave gravure plate with fine lines structures, conventional art used lithography with dry/wet etching. Lithography with dry/wet etching method allows to engrave lines with smooth concave shape, but its disadvantages include difficulty in controlling aspect ratio, high and uniform in large size process, substrate material limitation due to etching solution availability, and process complexity. We developed ultra-fast laser technology to directly engrave a stainless plate, a gravure plate, to be used for fabricating 23 in. metal-mesh touch panel by gravure offset printing process. The technology employs high energy pulse to ablate materials from a substrate. Because the ultra-fast laser pulse duration is shorter than the energy dissipation time between material lattices, there is no heating issue during the ablation process. Therefore, no volcano-type protrusion on the engraved line edges occurs, leading to good printing quality. After laser engraving, we then reduce surface roughness of the gravure plate using electro-polishing process. Diamond like carbon (DLC) coating layer is then added onto the surface to increase scratch resistance. We show that this procedure can fabricate gravure plate for gravure offset printing process with minimum printing linewidth 10.7 µm. A 23 in. metal-mesh pattern was printed using such gravure plate and fully functional touch panel was demonstrated in this work.
