Method for preparing ultrathin dielectric ceramic film based on particle-free dielectric ceramic ink
The invention discloses a method for preparing an ultrathin dielectric ceramic film based on particle-free dielectric ceramic ink. The particle-free ink consists of the following components in percentage by mass: 5-40% of a titanium precursor component, 5-40% of a barium precursor component, 10-70% of a complexing agent, 0-10% of an organic additive and 0-10% of ethyl cellulose, with the balance being a solvent. The preparation method comprises the following steps: firstly, fully dissolving a chelating agent or the complexing agent in the solvent in proportion, and then adding the barium precursor and the titanium precursor into the mixed solution until the barium precursor and the titanium precursor are completely dissolved to obtain the particle-free ink. The ceramic ink may include an additive component. The ceramic ink can be printed (through means such as intaglio printing, roll-to-roll printing and ink-jet printing) onto various substrates and decomposed at low temperature to form an ultrathin barium titanate film with the advantages of a high dielectric constant, low dielectric loss and the like. The preparation method is simple in process, low in curing temperature, short in time, high in stability and free of pollution, and can be widely applied to electronic devices such as electronic ceramics, thermistor elements and capacitors.
本发明公开了一种基于无颗粒型介电陶瓷墨水制备超薄介电陶瓷薄膜的方法。其中无颗粒墨水由下列质量百分含量的组分组成：5～40％钛前驱体组分、5～40％钡前驱体组分、10～70％络合剂、0‑10％有机添加剂、0‑10％乙基纤维素、其余为溶剂。首先按照上述比例将螯合剂或络合剂充分溶解于溶剂中，然后将将钡前驱体、钛前驱体加入到混合溶液至完全溶解后得到本发明的无颗粒墨水。该陶瓷墨水可包含添加剂组分。该陶瓷墨水可印刷(例如凹版印刷、卷对卷印刷、喷墨打印)至多种基材上且低温分解以形成具有高介电常数、低介电损耗等优点的超薄钛酸钡薄膜。制备方法简单，固化温度低，时间短，稳定性高，绿色无污染，在电子陶瓷、热敏电阻元件、电容器等电子器件中有广泛的应用。
