Recent Advances in Preparation of Graphene Conductive Inks by Liquid-phase Exfoliation

The work aims to review the current status of research on preparation of graphene conductive inks by liquid phase exfoliation, so as to provide references for further promoting the application of graphene conductive inks in printed electronics. The physical and chemical properties of the solvents and additives used, the preparation process, and the properties of the produced graphene conductive inks were summarized and compared for various methods of preparing graphene conductive ink by liquid phase exfoliation. Current research on graphene conductive inks prepared by liquid phase exfoliation mainly focuses on the enhancement of the conductive properties of the ink and the dispersibility of graphene. Future studies still need to pay attention to the selection of solvents and additives in the process of liquid phase exfoliation, and the development of the future graphene conductive ink should focus on low cost, green and industrialization.
