随着微流控技术的发展，带电液滴的电泳运动可以作为液滴驱动的方法，因此微米级水溶液液滴的带电特性受到越来越多的关注。本文提出了一种基于平行板电容模型研究微米级水滴荷电特性的新方法。利用该方法，研究了电场强度、电解质浓度和离子种类对水相液滴荷电特性的影响。实验结果表明，该方法可用于研究微米级液滴的荷电特性。
The charging characteristics of micrometer sized aqueous droplets have attracted more and more attentions due to the development of the microfluidics technology since the electrophoretic motion of a charged droplet can be used as the droplet actuation method. This work proposed a novel method of investigating the charging characteristics of micrometer sized aqueous droplets based on parallel plate capacitor model. With this method, the effects of the electric field strength, electrolyte concentration, and ion species on the charging characteristics of the aqueous droplets was investigated. Experimental results showed that the charging characteristics of micrometer sized droplets can be investigated by this method.
