基于喷墨和喷涂技术的溶液加工是在中等温度下利用前体溶液进行低成本现场陶瓷图案/薄膜制造方法之一。在本研究中，我们使用喷墨和喷涂技术在 300–400°C 的温度下直接在玻璃基板上制备二氧化钛陶瓷薄膜。通过将四异丙醇钛溶解在适当的溶剂（水/乙醇和乙酰丙酮）中来制备前体溶液。将清洗后的玻璃基板放置在热板上，加热至规定的温度。通过喷枪产生的前体溶液的液滴在大气压力下流向加热的基底。当液滴撞击到加热的基底上时，前驱体开始分解、成核并生长成 TiO2 薄膜。锐钛矿图案是在中等温度下通过喷墨方法直接获得的。
Solution processing based on Ink-jet and spray technologies is one of low cost on-site ceramic patterns/films fabrication methods at moderate temperatures from precursor solutions. In the present study, we have used ink-jet and spray technologies to fabricate ceramic films of titania directly on glass substrates at 300–400∘C. The precursor solution was prepared by dissolving Titanium tetraisopropoxide in appropriate solvents (water/ethanol and acetylacetone). A cleaned glass substrate was kept on a hot plate and heated it up to a predetermined temperature. Droplets of the precursor solution produced through a spray gun were traveled towards heated substrate with a atmospheric pressure. When the droplets hit on the heated substrate, precursor started to decompose, nucleate and grow into the TiO2 film. The anatase pattern was directly obtained by ink-jet method at moderate temperatures.
