“…Generally, high solid loading and low viscosity are required for applications such as micro-droplet jetting of alumina slurries [29], additive manufacturing of alumina magnesia silicate slurries [30], slip casting of magnesium aluminate spinel slurries [31], additive manufacturing of zirconia toughened alumina slurries [32], and dip coating of cerium oxide slurries [33]. Appropriate solid loading and viscosity are required for the inkjet printing of ceramic ink [34].…”

Recently, porous ceramics have received much attention from researchers because of their excellent thermal and chemical stabilities compared to their counterparts (such as porous polymers and metals), despite their inferior mechanical instability. Among the various types of porous ceramics, reticulated porous ceramics have significant industrial potential because of their synergistic high porosity and permeability. However, to the best of our knowledge, there is insufficient data on the processing conditions or preparing optimal reticulated porous alumina. Therefore, we prepared and characterized reticulated porous alumina specimens by controlling various processing conditions, namely average particle size, solid loading, binder, and dispersant. The data obtained were used to assess whether the compressive strength of the reticulated porous alumina could be enhanced and to discuss the potential of these materials for various applications.

“…It indicates rheological behavior of the colored nanosphere inks is Newtonian, with viscosities ranging from 1.5 to 5 mPa·s. Thus, the formulations include EG as a rheological modifier are suitable for DOD inkjet printing to avoid secondary phenomena, which usually happens for non-Newtonian liquid, such as sedimentation and dripping from nozzles [35].…”

Inkjet Printable and Self-Curable Disperse Dyes/P(St-BA-MAA) Nanosphere Inks for Both Hydrophilic and Hydrophobic Fabrics

et al. 2018

Low-water-soluble disperse dyes possess a broad color gamut and good durability, but they need chemical or physical modification before being used in inks and can only be applied to several kinds of hydrophobic fabrics. In this work, disperse dyes/P(St-BA-MAA) nanospheres (known as DPN) absorbed by sodium nitrilotriacetate (known as NTA@DPN) were prepared and applied into ink formulations, which exhibited high dye fixation, long-term stability and self-curable ability without addition of any binder. Transmission electron microscopy (TEM) images showed the nanospheres have homogeneous core-shell spherical shape and the average diameter increased by 20.6 nm after coloration. X-ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), and differential scanning calorimetry (DSC) measurements illustrated the interaction between dyes and nanospheres and indicated that the colored nanospheres contained both dye molecules and crystalline dyes. The Zeta potential and particle size measurements demonstrated that the dispersion stability was improved when sodium nitrilotriacetate (NTA) was absorbed onto DPN. The rheological behavior of the NTA@DPN inks was Newtonian and desired droplet formation was achieved at the viscosity of 4.23 mPa·s. Both hydrophilic cotton and hydrophobic polyester fabrics were cationic modified before used, which had an excellent image quality and desired rubbing fastness after inkjet printing. Scanning electron microscope (SEM) images showed NTA@DPN formed stable deposits on the surface of modified fibers and could self-cure to form continuous film coating on the fiber surface after being baked at 150 °C without addition of any binder.

“…The observed increase in PSD could be attributed to the increase in surface area of particles after 48 and 72 hrs milling at day 0, demanding more dispersant concentration to prevent them from flocculating. The weakening of colloidal stability in ceramic pigments due to prolonged milling has been reported in similar work on inkjet printability of aqueous based ceramic inks[56]. Hence, the effect of dispersant dosage was evaluated for 24 hrs milled samples based on the evolution of d90 on each sample after 7 days of ageing.…”
