Water dispersions of nanometric yttria stabilized zirconia (YSZ) particles synthesized by Continuous Hydrothermal Synthesis are transferred into nano-inks for thin film deposition. YSZ nanoparticles are synthesized in supercritical conditions resulting in highly dispersed crystals of 10 nm in size. The rheology of the colloid is tailored to achieve inkjet printability (Z) by using additives for regulating viscosity and surface tension. Inks with a wide range of properties are produced. A remarkable effect of nanoparticles on the ink printability is registered even at solid load < 1%vol. In particular, nanoparticles hinder the droplet formation at low values of the printability while suitable jetting is observed at high Z values, i.e. Z ≈ 20. For the optimized inks, we achieve high quality printing with lateral and thickness resolutions of 70 μm and ca. 250 nm respectively, as well as self-levelling effect with a reduction of the substrate roughness. Densification is achieved at sintering temperatures below 1200 °C.

通过连续水热合成法合成的纳米氧化钇稳定的氧化锆（YSZ）颗粒的水分散体被转移到纳米墨水中以进行薄膜沉积。YSZ纳米粒子是在超临界条件下合成的，产生了高度分散的10 nm大小的晶体。通过使用用于调节粘度和表面张力的添加剂，可调整胶体的流变性，以实现喷墨可印刷性（Z）。生产具有广泛性能的油墨。即使在固含量＜1％vol的情况下，纳米颗粒也对油墨的可印刷性产生了显着影响。特别地，纳米颗粒在低可印刷性值时阻碍液滴形成，而在高Z值下观察到合适的喷射，即Z≈20。对于优化的油墨，我们实现了横向和厚度分辨率分别为70μm和ca的高质量印刷。分别为250 nm和自流平效果，同时降低了基板的粗糙度。在低于1200°C的烧结温度下实现致密化。
