研究了金属基材的化学处理对超声波雾化器产生的气溶胶沉积的影响。使用具有不同亲水性（或疏水性）“水平”的区域的单一基底作为模型表面。根据表面电位计，处理过的（更亲水的）区域变得更加带负电。低压分析方法（电子显微镜图像）和常压方法（拉曼光谱和X射线荧光）分析结果表明，与未处理区域相比，处理区域在“湿”气溶胶沉积的情况下捕获了更多的颗粒。在沉积更多“干”气溶胶的情况下，未处理的区域比处理过的区域捕获更多的颗粒。颗粒沉积的效率不仅取决于表面的亲水性（或疏水性）程度，还取决于进入的气溶胶的条件（潮湿或干燥）。
The effect of chemical treatment of a metallic substrate on the deposition of aerosols generated by an ultrasonic nebulizer was investigated. A single substrate with areas having different “level” of hydrophilicity (or hydrophobicity) was used as a model surface. The treated (more hydrophilic) area became more negatively-charged based on a surface electric potential meter. A low-pressure analysis method (electron-microscope image) and ordinary pressure methods (Raman spectroscopy and X-ray fluorescence) analytical results indicated that in comparison with the untreated area, the treated area trapped more particles in the case of the deposition of “wet” aerosols. In the case of the deposition of more “dry” aerosols, the untreated area trapped more particles rather than that of the treated one. The efficiency of particles deposition not only depended on the degree of hydrophilicity (or hydrophobicity) of the surface but also due to the conditions (wet or dry) of incoming aerosols.
