Abstract We have investigated the processing of lead-zirconate-titanate-based thick films by inkjet printing Pb(Zr0.53Ti0.47)0.98Nb0.02O3 with a 6 mol% excess of PbO nanosized powder dispersed in water. Different waveforms were employed to determine the optimum size and shape of the drops. A uniform, defect-free pattern with dimensions of 4 mm × 4 mm can be printed using 20 V and a drop spacing of 20 μm. The inkjet-printed films were heated to 400 °C to remove the organics and subsequently sintered at 750 and 850 °C. The correlations between the density, grain size and electromechanical properties of the thick films and bulk ceramics are qualitatively discussed. A thickness coupling factor of 46% was obtained for a 15-μm-thick film sintered at low temperature of 850 °C, which is comparable to the value of the bulk ceramic with an identical nominal chemical composition. Our results are important for the economic and environmental-benign printing of piezoelectric materials applicable in variety of electronic devices, such as sensors, actuators, transformers, piezoelectric energy harvesters and transducers.

喷墨印刷衍生的锆钛酸铅基厚膜，用于印刷电子产品

摘要 我们研究了通过喷墨印刷 Pb(Zr0.53Ti0.47)0.98Nb0​​.02O3 和 6 mol% 过量的 PbO 纳米尺寸粉末分散在水中来加工锆钛酸铅基厚膜。采用不同的波形来确定液滴的最佳尺寸和形状。可以使用 20 V 和 20 μm 的液滴间距打印尺寸为 4 mm × 4 mm 的均匀、无缺陷图案。将喷墨印刷的薄膜加热到 400 °C 以去除有机物，然后在 750 和 850 °C 下烧结。定性地讨论了厚膜和块状陶瓷的密度、晶粒尺寸和机电性能之间的相关性。对于在 850 °C 的低温下烧结的 15 μm 厚的薄膜，获得了 46% 的厚度耦合系数，这与具有相同标称化学成分的大块陶瓷的值相当。我们的结果对于适用于各种电子设备（例如传感器、致动器、变压器、压电能量收集器和换能器）的压电材料的经济和环境友好型印刷具有重要意义。
