“…Recently Perelaer et al developed a one-step inkjet process to produce metal lines on glass and on plastic foils [204]. Silver salt ink with viscosity of 10 cP was jetted directly onto the pre-heated substrate triggering solvent evaporation and sintering as a combined process.…”

Abstract:A review on applications of metal-based inkjet inks for printed electronics with a particular focus on inks containing metal nanoparticles, complexes and metallo-organic compounds. The review describes the preparation of such inks and obtaining conductive patterns by using various sintering methods: thermal, photonic, microwave, plasma, electrical, and chemically triggered. Various applications of metal-based inkjet inks (metallization of solar cell, RFID antennas, OLEDs, thin film transistors, electroluminescence devices) are reviewed.

“…Wettability plays a key role in various industrial applications (e.g., material dispersion and interfacial chemistry). In particular, it significantly affects the coating industry, which includes nano engineering, ink, paint, paste, and adhesives; as well as the compound industry, which includes extrusion, injection molding, and casting [8][9][10][11][12][13]. Surface energy is the energy created by surface atoms, and is the result of the force of attraction they exert on external materials.…”

Graphite is a material condensed from aromatic hydrocarbon that forms an infinite plane that exhibits an amphoteric feature. Structurally, a number of benzene rings form a solid planar sheet. A number of layers are formed from numerous unit cells, a so-called grapheme. A graphene sheet has an electron structure, which expands π-electrons into a two dimensional space. Graphite has AB-stacked bilayers of graphene. Because the interaction between two sheets is weak, their electronic structure may vary significantly. In addition, because graphite has either zero-semiconductor electronic structures, or a semi-metal electronic structure, its ionization energy is 4 eV [1] and it has dual electronic characteristics. Thus, it may work as either an oxidizer or reducer. In particular, the shape of the graphite plays an important role in its mechanical characterization [2]. Graphene, in its role as a unit cell of graphite, is known to have great potential for applications in many fields [3]. It is critical to understand graphite's interfacial interaction with a matrix, or its wettability, when applying its electrically and thermally conductive properties to characteristic composites.In this study, we proposed a simple method by which to determine the surface energy of graphene to expand graphite applications and to understand better the interfacial interaction of various matrices. This will explain why strong acids (e.g., sulfuric acid and nitric acid [4][5][6][7]) are employed for graphene or graphene oxide synthesis. In order to implement these kinds of experiments, repetitive work and trial-and-error are unavoidable. However, if we are able to understand the surface energy of graphite, we can save time and effort as well as facilitate systematic approaches by which we can choose appropriate solvents and chemicals.The surface energy could be represented in terms of wettability and contact angles. Wettability plays a key role in various industrial applications (e.g., material dispersion and interfacial chemistry). In particular, it significantly affects the coating industry, which includes nano engineering, ink, paint, paste, and adhesives; as well as the compound industry, which includes extrusion, injection molding, and casting [8][9][10][11][12][13]. Surface energy is the energy created by surface atoms, and is the result of the force of attraction they exert on external materials. Higher surface energy promotes greater liquid wettability. Therefore, the higher the surface energy is, the more enhanced the wettability, and the smaller the contact angle, becomes. As a result, knowing the droplet contact angle will determine the corresponding surface energy. The density of surface energy for water is 72 mJ/m 2 and its surface tension is 72 mN/m. Their values are the same. In order to measure the droplet contact angle, a planar surface and knowledge of the compact density of the given materials are required. In the case of graphite, it is difficult to acquire a planar surface. However, in this study, we report a simple meth...

“…These MOD inks have been used for inkjet printing since the late 1980s (Vest et al, 1983). In order to obtain metal features, a conversion of organometallic silver inks is required, which usually takes place at relatively low temperatures below 200 °C (Wu et al, 2007), although temperatures below 150 °C have been reported as well (Smith et al, 2006, Perelaer et al, 2009a. The typical metal loading of organometallic inks is 10 to 20 wt%.…”
