【摘要】：喷墨打印是一种将功能材料进行图案化沉积的手段,具有方法简便、成本低廉、灵活快速等优点,成为了最具前景的图案化方法之一,在功能器件研究应用领域受到了广泛关注。"咖啡环"效应是喷墨打印过程中一种常见的现象,它会导致功能材料的不均匀沉积,影响打印图案的分辨率以及所制备功能器件的性能。因此,"咖啡环"效应的研究对于喷墨打印图案精度及功能器件性能极为重要。本文综述了近年来液滴蒸发过程中"咖啡环"效应的研究进展,阐述了"咖啡环"效应的产生机理及抑制"咖啡环"效应的方法,并进一步介绍了抑制或利用"咖啡环"效应在喷墨打印制备高性能器件,如高质量光子晶体图案、高灵敏度传感器、半导体薄膜、透明导电膜、短沟道晶体管等方面的应用。最后,探讨了目前"咖啡环"效应在喷墨打印应用中仍需解决的问题,展望了调控喷墨打印过程中"咖啡环"效应与纳米材料相结合的广阔研究应用空间。这些工作将会对功能材料图案化、高性能器件制备及3D打印等具有重要意义。
[Abstract]:Inkjet printing is a method of patterning and depositing functional materials. It has the advantages of simple method, low cost, flexibility and rapidity, and has become one of the most promising patterning methods. In the field of research and application of functional devices, widespread attention has been paid. " The coffee-ring effect is a common phenomenon in inkjet printing. It can lead to uneven deposition of functional materials and affect the resolution of printing patterns and the performance of functional devices. Therefore, the study of "coffee ring" effect is very important for ink-jet printing pattern accuracy and functional device performance. In this paper, the research progress of "coffee ring" effect in the process of droplet evaporation is reviewed, the mechanism of "coffee ring" effect and the method of restraining "coffee ring" effect are expounded. The applications of suppressing or utilizing "coffee ring" effect to fabricate high performance devices such as high quality photonic crystal pattern, high sensitivity sensor, semiconductor film, transparent conductive film, short channel transistor and so on are also introduced. Finally, the problems that need to be solved in the application of "coffee ring" effect in inkjet printing are discussed, and the wide research and application space of "coffee ring" effect combined with nano-materials in the process of regulating ink jet printing is prospected. These works will be of great significance to the patterning of functional materials, fabrication of high performance devices and 3D printing.
