We study the influence of inkjet printing scheme and sintering parameter on the electrical resistivity of multi-layer silver nanoparticle films. A central composite Design Of Experiments (DOE) is employed to maximize experimental efficiency and improve the statistical significance of parameter estimates. The resulting mathematical correlations allow to interpret the influence of the print and sintering parameters. Detailed inspection of the correlations reveals the existence of local extrema and indicates that a structured approach such as the DOE would be significantly more effective for fabricating films with a minimum of resistivity. Furthermore, we modify the well-known Fuchs-Sondheimer Mayadas-Shatzkes model to correlate the resistivity of a multi-layer nanoparticle film with the sintering temperature and time. The modified model uses literature data but one constant inferred from two experiments. After model adjustment, the resistivities of films fabricated with different parameters can be predicted with good accuracy. This validation tremendously increases applicability and relevance of the model.
我们研究了喷墨打印方案和烧结参数对多层银纳米颗粒薄膜电阻率的影响。采用中心复合实验设计（DOE）来提高实验效率并增强参数估计的统计显著性。由此得到的数学关联关系有助于解释打印和烧结参数的影响。对这些关联关系的详细考察揭示了局部极值的存在，并表明像DOE这样的结构化方法对于制造具有最低电阻率的薄膜将显著更有效。此外，我们修改了著名的富克斯 - 桑德海默 - 马亚达斯 - 沙茨克斯模型，以关联多层纳米颗粒薄膜的电阻率与烧结温度和时间。修改后的模型使用了文献数据，但有一个常数是从两个实验中推断出来的。经过模型调整后，可以很好地预测用不同参数制造的薄膜的电阻率。这种验证极大地提高了该模型的适用性和相关性。
