Two-dimensional (2D) van der Waals (vdW) materials are considered one of the most promising candidates to realize emerging electrical applications. Although until recently, much effort has been dedicated to demonstrating high-performance single 2D vdW devices, associated with rapid progress in 2D vdW materials, demands for their large-scale practical applications have noticeably increased from a manufacturing perspective. Drop-on-demand inkjet printing can be the most feasible solution by exploiting the advantages of layered 2D contacts and advanced 2D vdW ink formulations. This review presents recent achievements in inkjet-printed 2D vdW material-based device applications. A brief introduction to 2D vdW materials and inkjet printing principles, followed by various ink formulation methods, is first presented. Then, the state-of-the-art inkjet-printed 2D vdW device applications and their remaining technical issues are highlighted. Finally, prospects and challenges to be overcome to demonstrate fully inkjet-printed, high-performance 2D vdW devices are also discussed.
二维（2D）范德华（vdW）材料被认为是实现新兴电气应用最有前途的候选材料之一。尽管直到最近，人们都致力于展示高性能的单个2D vdW器件，随着2D vdW材料的快速发展，从制造角度来看，对其大规模实际应用的需求显著增加。按需滴注喷墨印刷通过利用分层2D接触和先进的2D vdW油墨配方的优势，可能是最可行的解决方案。本文综述了喷墨印刷的基于2D vdW材料的器件应用的最新成果。首先简要介绍2D vdW材料和喷墨印刷原理，然后介绍各种油墨配方方法。接着，重点介绍了最新的喷墨印刷2D vdW器件应用及其剩余的技术问题。最后，还讨论了要展示完全喷墨印刷的高性能2D vdW器件需要克服的前景和挑战。
