臺灣博碩士論文加值系統

本論文探討接觸角量測實驗時，試片準備、環境之有機氣體與水氣、及接觸角量測儀之量測誤差對於接觸角量測結果的影響。發現相機俯角越大，量測誤差會越大，不過液滴等於90°時，量測值並不會受相機俯角的影響；當液滴接觸角小於90°時，接觸角越小，相機俯角造成的量測誤差會越大，反之，液滴大於90°時，接觸角越大，相機俯角造成的量測誤差也會越大。另外，清洗過的基板在乾燥時需放入真空腔體並經過加熱程序，才能有效去除有機分子與水氣的附著。在探討有機分子、水氣對接觸角量測實驗結果之影響時發現，有機分子會影響固體材料之極性表面自由能^p的量測值，影響程度與材料原本的極性表面自由能值有關；水氣會影響固體材料之非極性表面自由能^d的量測值，影響程度與材料原本的非極性表面自由能值有關。
瞭解上述的影響後，提出一個接觸角量測實驗的標準量測流程，讓之後的實驗者按照此流程進行實驗，可突破氣候與地區的限制、降低實驗者人為因素、以及忽略接觸角量測儀器間的規格差異，得到更一致且準確的量測結果。
另外，提供以此標準量測流程所量測之接觸角估算得出的實驗室常見固體的表面自由能，作為日後實驗者的參考依據。

This paper discusses the influence of some common factors in laboratory which have always been ignored during contact angle measurement such as sample preparation, organic gases and water vapor, and measurement lack of goniometer.
It is found that if the contact angle of droplet is equal to 90°, the measured contact angle of droplet won’t change when depression angle increases；If the contact angle is less than 90°, the smaller the contact angle is, the larger the measurement error happened due to the increasing depression angle; However, if the contact angle is more than 90°, the larger the contact angle is, the larger the measurement error happened due to the increasing depression angle.
In sample preparation, the cleaning samples have to be hold in closed vacuum chamber and heated during drying process in case the adsorption of organic compound and water vapor.
In addition, when discussing the effects of organic gases and water vapor to surface of solid materials, the conclusion is, organic gases will influence the polar component of surface free energy of the solid surface, while water vapor influences the nonpolar component.
According to the results above, our laboratory suggested a standard procedure of contact angle measurement. Let the following operators who use this procedure can eliminate the environment factors wherever they belong to. And finally, we supplied the surface free energy datasheet of some common solid materials.
