粘附功(work of adhesion)
讨论1. What is the work of adhesion? (转摘自:https://www.biolinscientific.com/blog/work-of-adhesion-what-is-it-and-how-to-measure-it)
a.定义:粘附功W12是指从相邻两相1和2之间分离需要做的功,可以是液液之间或者液固相界面。
b.计算方法如下:

同时,它也是润湿过程中释放的能量。粘附功的单位是J/m2。
3.表面化学-粘附功和粘附力 (转摘自:https://mp.weixin.qq.com/s/PyPl_KmqXp6UECQX3V4ksg)
讨论4.粘附功的另外算法in MD simulation
通过体系的总能量来计算,公式如下:
W12 = {(E1 + E2)- E12}/2A
(该算法来自文献:Computer simulation of polyolefin interfaces,1999)
