| dc.description.abstract | 在微流道中兩液滴碰撞的結果及了解結果的機理很重要。含有三矽甲烷介面活性劑的二甲基甲酰胺液滴可以在聚（甲基丙烯酸甲酯）基質上隨機地自發性移動。當自推進液滴遇到另一個靜態液滴時，出現一些有趣的現象，並歸納出四種類型：（i）吞噬並帶走（液體石蠟），（ii）吞噬並釘札（橄欖油），（iii）繞行後離開（水）和（iv）反彈並離開（甘油）。在吞噬的類型中發現兩接觸液體互不相溶，而反彈的種類中則輕易地溶解在一起，前者可以用兩個擴展係數來解釋，而後者可以歸因於接觸時界面張力梯度的建立。 | zh_TW |
| dc.description.abstract | Understanding the outcome and mechanism of droplet-droplet collision is important in digital microfluidics. A dimethylformamide droplet containing Silwet L-77 can self-propel randomly on poly(methyl methacrylate) substrates. When the self-propelled droplet encounters another static liquid droplet, some interesting phenomena appear and they can be generally classified into four types: (i) swallow-and-run (liquid paraffin), (ii) swallow-run-pinning (olive oil), (iii) detour-and-run (water), and (iv) recoil-and-run (glycerol). The swallow behavior is observed as the two droplets are immiscible, but the rebound behavior is acquired as they are miscible. The former can be explained by the two spreading coefficients, while the latter may be attributed to the buildup of the gradient of the interfacial tension upon contact. | en_US |
