Pristine and sp³-functionalized
(6,5) SWNTs were printed under identical conditions. Toluene and terpineol
(mixture of isomers, Sigma-Aldrich) were added to the dispersion to
adjust the SWNT concentration to 5.4 mg L^–1 (E₁₁ absorbance of 3 cm^–1) and
the terpineol concentration to 2 vol-%. This ink was used for aerosol
jet printing (Aerosol Jet 200 printer, Optomec) with an ultrasonic
atomizer.^{63 (link),64 (link)} A 200 μm inner diameter nozzle was
used at a sheath gas flow of 30 sccm and carrier gas flow of 25 sccm.
The film thickness was tuned by the number of printing cycles. The
sample stage was at 100 °C to facilitate fast evaporation of
Toluene. Residual terpineol was rinsed off with tetrahydrofuran and
isopropyl alcohol.

Example 11

Ink Preparation and Characterization: Graphene-EC powder (0.5 g) and EC (0.5 g, Aldrich, 4 cP at 5 wt. % in toluene/ethanol 80:20) was dispersed in ethanol (˜25 mL) and terpineol (5.0 mL, Aldrich, mixture of isomers, anhydrous) by bath sonication for ˜90 min. The dispersion was passed through a 3.1 μm glass fiber filter membrane (Acrodisc®). The filtered dispersion was heated on a hot plate to remove ethanol, yielding a final ink of 20% w/v solids in terpineol, with a graphene:EC ratio of 2:3 by weight (Ink 1). The higher viscosity ink (Ink 2) was prepared similarly using a higher viscosity EC sample (Aldrich, 22 cP at 5 wt. % in toluene/ethanol 80:20). In this way, the two inks are characterized by nominally equivalent graphene concentration and total solids loading but exhibit viscosity varying by about one order of magnitude. The shear viscosity of the inks was measured using a Physica MCR 300 rheometer equipped with a 25 mm, 2° cone and plate geometry at shear rates of 0.1-1000 s⁻¹The temperature was controlled by a Peltier plate at 25° C.

Fluorine-doped tin oxide (FTO) substrates (Pilkington, TEC8, 8 Ω cm⁻²) were undergone surface preparation including pattern etching and ultrasonically cleaning in acetone, detergent and ethanol for 30 min per each. A dense TiO₂ blocking layer (bl-TiO₂) was deposited on the FTO via the spray pyrolysis method from a solution of titanium diisopropoxide bis(acetylacetonate) (Aldrich) diluted in ethanol (v/v, 1/10) at 450 °C. Then, a 200-nm thick mesoporous TiO₂ (mp-TiO₂) layer was fabricated on the substrates by spin coating a TiO₂ commercial paste (containing TiO₂ nanoparticles: average diameter: 50 nm, anatase) diluted in 2-methoxyethanol and terpineol (Aldrich) solution followed by annealing at 500 °C for 60 min and cooling to room temperature.

Ink Preparation and Characterization: Graphene-EC powder (1.0 g) was dispersed in ethanol (˜25 mL) and terpineol (10 mL, Aldrich, mixture of isomers, anhydrous) by bath sonication. This dispersion was passed through a 3.1 μm glass fiber filter membrane (Acrodisc®). The filtered dispersion was heated on a hot plate to remove ethanol, yielding a final ink of 10% w/v solids in terpineol (Ink 1, FIG. 2A). The medium and low viscosity inks (Inks 2 and 3, FIG. 2A, respectively) were prepared by a similar technique with different concentrations (7.2% w/v and 5% w/v solids, respectively). The shear viscosity of the inks was measured using a Physica MCR 300 rheometer equipped with a 25 mm, 2° cone and plate geometry at shear rates of 1-1000 s⁻¹.

Dispersion and Ink Formulation for Ceramic Printing

Check if the same lab product or an alternative is used in the 5 most similar protocols

10 mol% gadolinium doped cerium (IV) oxide (Sigma-Aldrich), NiO (Sigma-Aldrich) and hydroxypropyl cellulose (Sigma-Aldrich) powders were milled in terpineol with 3YSZ milling balls in a planetary mill for 8 h to ensure average particle sizes of ~400 nm, D90 (measured by Zetasizer 3000HS, Malvern Instruments). hydroxypropyl cellulose was used as polymeric dispersant for steric ink stabilization (2 wt% of the NiO or CGO powder base). It also acted as a binder and a relief for drying stresses [35 (link)] as well as a fugitive agent in the creation of the porous scaffold. The inks were adjusted to the required viscosity range by varying the amounts of binder and diluting solvent. Methanol was chosen as a diluting solvent readily dissolving the polymeric dispersant and allowing for fast drying of the drops. terpineol (Sigma-Aldrich) was selected as low vapour pressure solvent, inducing Marangoni flows counteracting the formation of coffee-ring stains [36 (link)]. It also played the role of a natural dispersant for the oxide particles having excellent miscibility with the polymeric dispersant and the methanol solvent. The dilution at volume ratio 1:1 (terpineol:methanol) was chosen based on stable jetting optimization procedure discussed below.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
