Surface−energy/surface−tension 1.Surface tension 1.1 How does surface tension generate? 通过很多现象(量筒度数、满水不溢)可以发现水像绷紧的膜一样。本点着重探究该现象的原因。 内容 定义:液体表面就像张开的橡胶膜一样,有一种收紧的趋势。这种使得液体表面收缩的力称之为表面张力。其来源是液体的内层...
- 《Energy & Fuels》 被引量: 72发表: 1994年 Surface tension of bitumen from contact angle measurements on films of bitumen Advancing contact angles, theta/sub A/, of water and glycerol were measured on films of bitumen. The bitumen was obtained by extracting different raw oil s... EI ...
Surprisingly, although water droplets should obtain perfect wetting on high-energy surfaces (i.e., the contact angle should be close to zero degrees according to Young's equilibrium equation), in fact non-zero contact angles are obtained in most cases. This is obviously related to the extremely...

, where γsv is the surface free energy, γsl is the interfacial tension between the liquid and the solid, γlv is the surface tension of the liquid, and θY is the contact angle on a surface. Out of these, the surface tension of the liquid and the contact angle can be easily measu...
Then, we perform contact angle measurements once more, and the corresponding surface energy differences are plotted as squares in Fig. 3. As can be seen in these plots, the value of γsv − γsl is now constant with respect to the pre-applied strain ε. These data intersect the ...
