研究目的
Investigating the use of solutions of metal alkoxoacetylacetonates as functional inks for ink-jet printing of TiO2-10%ZrO2 thin nanostructured films for oxygen detection.
研究成果
The study demonstrated the successful use of metal alkoxoacetylacetonates solution as a functional ink for ink-jet printing of TiO2-ZrO2 thin films. These films showed high sensitivity to oxygen at operating temperatures of 350-450°C, with potential applications in oxygen detection in various environments.
研究不足
The study is limited by the specific composition of the ink and the conditions under which the films were prepared and tested. Potential areas for optimization include the ink formulation and the printing process to improve film uniformity and sensitivity.
1：Experimental Design and Method Selection:
The study utilized a solution of metal alkoxoacetylacetonates in isoamyl alcohol as a functional ink for ink-jet printing. The anatase crystal lattice was formed during heat treatment at 500°C.
2：Sample Selection and Data Sources:
Thin films of TiO2-10%ZrO2 were printed on a polycrystalline Al2O3 substrate with platinum interdigital electrodes.
3：List of Experimental Equipment and Materials:
Equipment included a Dimatix DMP-2831 printer, SEM Zeiss Supra 40-30-87, and a Fluke 8846A digital multimeter. Materials included titanium (IV) n-butoxide, zirconium oxide dichloride hydrate, and acetylacetone.
4：Experimental Procedures and Operational Workflow:
The solution was printed, dried, and calcined to form the ceramic layer. Gas-sensitive properties were studied in a gas cell at temperatures of 300-450°C.
5：Data Analysis Methods:
The electrical resistance of oxide films was measured, and responses to gases were calculated using specific formulas.
