Sažetak
Glass is a versatile material well known for several thousands of years, indispensable in a broad spectrum of applications even today – from conventional rigid electronics and structured glass decorations, to novel bioactive glass ceramics and active smart-layer systems1. The long-standing challenge in this field is to synthesize novel and multifunctional coatings that can be conveniently and economically fabricated on the glass surface. For this purpose, inkjet- printing of solution-processable nanomaterials has emerged as an innovative digital and cost- effective fabrication technique for the deposition of mosaic thin film geometries on glass substrates. In this work, a colloidal suspension containing 10 wt% of silver nanoparticles (AgNPs) in a ternary solvent mixture was used as the glass coating material. Multiple ink layers were deposited in a single pass using inkjet-printing technology and sintered both thermally and with intense pulse light (IPL) to produce high-resolution conductive and customized decorative silver patterns. To ensure appropriate adhesion of the functional nanosilver material to the heterogeneous adsorption sites of the glass surfaces, i.e., to provide both electrical and decorative functionality, the polyacid-stabilised AgNPs were additionally functionalized with a propylamine moiety to precisely tune the hydrophylic- hydrophobic interactions2. A thorough characterization of the nano-ink suspension (chemical functionality, colloidal stability, particle size distribution, rheology and wettability) and the characterization of the silver thin film (uniformity, surface composition and roughness, electrical features), were performed experimentally (UV-Vis spectroscopy, dynamic light scattering (DLS), zeta-potential and contact angle measurements, AFM images) and supported by theoretical calculations (density functional theory, DFT). Remarkable electrical properties of the silver coating (sheet resistance of 0.27 Ω sq–1) were determined using a four-point probe.
