There is a significant industrial demand for minimizing the size of droplets for various technical applications. Herein, conformal polymer coatings were used to decrease the orifice dimensions of aperture plates to almost any desired dimension. The generated droplet size revealed a relevant impact on the final dried particle size in a spray-drying process. Likewise, the smaller droplets generated resulted in an improved lung deposition following inhalation. Overall, the current results help increase the understanding on how to manipulate the size distribution of droplets produced by actuated aperture plates, especially in the sub-10 μm range.

涂有聚合物的孔板，用于量身定制的雾化工艺

对于各种技术应用，存在最小化液滴尺寸的巨大工业需求。在本文中，使用保形聚合物涂层将孔板的孔尺寸减小到几乎任何期望的尺寸。产生的液滴尺寸揭示了对喷雾干燥过程中最终干燥颗粒尺寸的相关影响。同样，产生的较小液滴可导致吸入后改善的肺部沉积。总的来说，目前的结果有助于增加对如何控制由致动孔板产生的液滴尺寸分布的理解，尤其是在10μm以下的范围内。
