| Popis: | Multinozzle printing processing with the fabrication of a functional material film lays the foundation for the development of efficient scale production of a photoelectric device. However, a prominent challenge is how to realize the volume uniformity of the droplets. Here, a classical analysis method is introduced first by printing poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) to analyze the behavior of droplets. It relies on a variance calculation for the clarification of the law of implicit behavior of droplets in terms of digitizing. This method reveals the effect of printing parameters on the uniformity of the volume of droplets in multinozzle printing. Overall, by combining both ink formulations and printing parameter optimization, it is concluded that the minimum volume variance of nozzles with different numbers is less than 0.5% and the influence of various parameters in multinozzle printing is found to be ranked. The feasibility of this analysis method is presented and is of great significance to achieving a very stable, large-scale multinozzle printing device. |
