The sessile drop is the standard arrangement for optical measurement of the contact angle using drop shape analysis.
初步的结论是,Sessile Drop法时,两家德国公司的测试数据区别挺大,特别应于界面张力值测试时,而RealDrop法时,目前的效果可以,但需要分析更多的数据,以进一步求证数据的真实可靠性。通常Sessile Drop法,酒精、苯这样的液体与材料的接触角值比较小,而疏油材料通过是通过表面处理的,其真实界面张力或表面自由能值已经有所...
We find that the simpler condition can describe the inflection point and cusp of the axisymmetric drop if the solid-liquid interface is no longer assumed to be flat. The solution is now checked asymptotically for large and small time and for short distances from the tri-junction condition....
Asessile dropunder the influence of gravity has a flattened shape due to its own weight. The deviation from the shape of a sphere or spherical cap is greater the larger the weight and the lower thesurface tension. If the dimensions and density of the drop are known, thesurface tensioncan ...

The experimental results provide evidence for the relationship between thermo-capillary instabilities and the measured critical height of the sessile drop interface. There is also evidence of the effects of microgravity and Earth conditions on the sessile drop evaporation rate, and the shape of the ...
座滴法(SessileDrop)或貼泡法(CaptiveBubble) 座滴法是測量接觸角的光學方法。 此法用來估計固體表面某一局部區域的潤濕性。 可直接測量介於液滴基線和液/固/氣-三相接觸點 處的液/固-界面切線間的角度(接觸角)。 除ㄧ般的平面固體表面外,也適合測量彎曲固體 ...
