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.
通过制造功能材料薄膜的多喷嘴印刷工艺为高效规模化生产光电器件奠定了基础。然而，一个突出的挑战是如何实现液滴的体积均匀性。在此，首先引入一种经典分析方法，即通过印刷聚（3,4-乙撑二氧噻吩）/聚（苯乙烯磺酸盐）（PEDOT:PSS）来分析液滴行为。它依靠方差计算来从数字化角度阐明液滴隐含行为的规律。该方法揭示了印刷参数对多喷嘴印刷中液滴体积均匀性的影响。总体而言，通过结合油墨配方和印刷参数优化，得出不同数量喷嘴的最小体积方差小于0.5%，并且发现了多喷嘴印刷中各种参数的影响排名。提出了这种分析方法的可行性，这对于实现非常稳定的大规模多喷嘴印刷设备具有重要意义。
