本文研究了纳米微粒液滴在喷墨薄膜表面的沉积特性，利用喷墨打印设备制造不同参数的氧化铝薄膜，讨论薄膜温度和厚度对墨滴铺展面积以及边缘质量的影响。结果表明，提高薄膜温度和厚度均能改善液滴沉积面积和边缘质量，圆度能够提高约28%，一种有效的提高打印质量的方法；增大薄膜厚度能够缩小液滴沉积面积，但是存在临界值导致面积不变；薄膜增厚策略对沉积面积的影响较小，会影响薄膜表面质量进而影响液滴沉积的边缘质量。

The deposition characteristics of nanoscale particle droplets on inkjet-printed thin films were investigated. Different parameters of alumina films are fabricated using an inkjet printing device, and the effects of film temperature and thickness on droplet spreading area and edge quality are discussed. The results indicate that increasing both film temperature and thickness can enhance the deposition area and edge quality of droplets, resulting in a roundness improvement of approximately 28%, which proves to be an effective method for enhancing print quality. Moreover, it is observed that increasing film thickness initially reduces the deposition area but reaches a critical value beyond which no further reduction occurs. Although thickening the film has a minor impact on the deposition area, it significantly affects surface quality, thereby influencing the edge quality of droplet deposition.
