| Summary: |
The final aim of this project is to optimize the printability of 2D-material-based (graphene, TMDs and h-BN) inks to overcome the current limitations related with printed electronics and allow them going from niche to mainstream market. We will perform an in-depth rheological characterization of new formulations and 2D-inks currently available in literature for printed electronics. The three processes associated with the inkjet printing technologies (continuous inkjet printing, drop-on-demand and electroestatic
inkjet printing) will be assessed in terms of fluidic deficiencies by a thorough fluidflow characterization at lab-scale. Finally, two approaches for the optimization will be followed: 1) Based on the rheological properties of the inks, the geometry of nozzle and the printing conditions will be numerically optimized; and 2) based on the fluid-flow dynamics occurring during the printing conditions of each technique, the formulation of the inks will be optimized. |
