“…The dispersions with a zeta potential value of less than -30 mV are considered strongly as stable [45]. When the conductive ink production is considered, the conductivity value which should be maximized [46]. The factor levels that affect on the dispersion properties have been selected with regard to the preliminary test results and GO and rGO synthesis procedure in the literature [1-2, 32, 47-53].…”

[20]. In many industrial applications, the stability of graphene oxide dispersions plays a crucial role for the proper solvent preparation. Therefore, many researchers have done the studies to understand the dispersion behavior and to improve the dispersion stability. Konios et al. [21] prepared GO and reduced graphene oxide (rGO) dispersions with the different solvents and they showed that the GO and rGO samples forms a stable dispersion with the deionized-water, ethylene glycol and N-methyl-2-pyrrolidone (NMP). Taha-Tijerina et al. [22] prepared a dispersion with the deionized-water, ethylene glycol, ethanol and mineral oil and they illustrated that the GO samples forms a strong stable dispersion with the deionized-water and ethylene glycol. Graphene oxide-deionized water nano-fluids are more attractive options because of the formation of fairly strong stable dispersions with graphene oxide in the deionized water and the elimination of toxic solvents such as NMP.The quality of the dispersions including "strong stability" can be represented with some criteria such as zeta potential value, thermal and electrical conductivity, pH, and particle size. Therefore, many studies have been done to analyze the GO dispersion properties. The average particle size and zeta potential value [22] [29] were analyzed without using any systematic analyzing such an experimental design approach. It has been determined that oxidants and pH of the

“…Consequently, it is widely used in an industrial setting for document printing, for printing graphic arts, and for package printing [1]. More recently, inkjet technology has successfully been employed for additive manufacturing, including electronic components [4][5][6][7][8][9][10][11][12], pharmaceuticals [13], biomaterials [14][15][16][17], and ceramic components [18].…”

Piezoacoustic drop-on-demand (DOD) inkjet printing is widely applied in high-end digital printing due to its unprecedented precision and reproducibility. Micron-sized droplets of a wide range of chemical compositions can be deposited; however, the stability of piezoacoustic DOD inkjet printing can sometimes be compromised through the stochastic entrainment of bubbles within the ink channel. Here, bubble nucleation, translation, and growth are studied in an experimental silicon-based printhead with a glass nozzle plate using high-speed imaging that is triggered by changes in the ink-channel acoustics. It is found that impurities in the ink can trigger bubble nucleation upon their interaction with the oscillating meniscus. Cavitation inception on a dirt particle during the rarefaction pressure wave is identified as a second mechanism for bubble formation. The acoustic driving pressure within the ink channel, and its change upon bubble nucleation, are obtained from a fit of a Rayleigh-Plesset-type bubble-dynamics equation to the measured time-resolved radial dynamics of the bubble. The measured decrease in channel resonance frequency after bubble entrainment results in a 24% increased ink-jet length. The nucleated bubbles translate toward the ink-channel walls due to acoustic radiation forces and ink streaming. The convective ink flow is characterized using high-speed particle-tracking velocimetry. The vortical flow near the oscillating meniscus is shown to trap the impurities, thereby increasing the particle-to-meniscus interaction probability and, correspondingly, the bubble-entrainment probability.

“…Wang et al [24] constructed a graphene oxide based thin film nanocomposite (TiO 2 @GO) membrane for nanofiltration (NF), which was observed to possess superior NF performance in the case of 0.2 wt% TiO 2 @GO with water flux of 22.43 L•m −2 •h −1 at 0.4 MPa. Majee et al [25] reported an efficient inkjet printing of water-based pristine GNPs ink. The combination of aqueous iodine doping and thermal annealing at elevated temperature can achieve an unprecedented DC conductivity of ~10 5 S•m −1 for inkjet printed GNPs films.…”

In this paper, graphene@cuprous oxide (rGO@Cu 2 O) nanocomposite was designed and prepared with graphene oxide, CuSO 4 , NaOH and L-ascorbic acid via an in-situ reaction process, and the as-prepared rGO@Cu 2 O nanocomposite was characterized by XRD, FT-IR, Raman spectroscopy, XPS, SEM-EDS and TEM. The results reveal that the rGO@Cu 2 O nanocomposite is of homogeneous distribution, and the Cu 2 O nanoparticles adsorbed on graphene sheets are with a fairly uniform size of 2.3 nm. The rGO@Cu 2 O/acrylic resin self-polishing marine antifouling paint with functional surfaces was also prepared in this work, and a series of measurements were carried out for the obtained product. The WCAs of paint is up to 113˚, and the adhesive force is averaged to 3.69 MPa. After being immersed into seawater, the whole bared panels show an abundant growth of marine organisms within 90 days, but the rGO@Cu 2 O paint coated surfaces are hardly fouled by marine organisms within 365 days. This work demonstrates that in situ synthesis of rGO@Cu 2 O is a tin-free potential alternative to inhibit biofouling.
