Progress in the preparation and ink-jet printing of 2D material-based nano-inks
Two-dimensional materials represented by graphene possess excellent comprehensive performance,which can be used to manufacture functional nano-inks and obtain optoelectronic functional devices by ink-jet printing.There are broad application prospects in the fields of energy,environment,life and health.This paper systematically summarized the properties of several typical two-dimensional materials,the preparation of nano-inks and the application of ink-jet printing,focusing on the regulation of liquid phase exfoliation and ink-jet printing processes.Different exfoliation methods and principles were summarized and compared,as well as the related theories of ink-jet printing,such as the coffee ring effect and Marangoni effect,were reviewed.Through the precise regulation of the two-dimensional material exfoliation process and its nano-inks printing process,it was expected to form an advanced micro-nano manufacturing technology based on ink-jet printing,realize the low-cost processing of different functional micro-nano electronic components and devices,and promote the development of biosensing,flexible electronics and other fields.
