And it turns out that microscopically rough surfaces tend to be more hydrophobic, because they can trap pockets of air and minimize the interaction between water droplets and the surface of the material.

结果显示，显微，糙的表面拥有更好的疏水性，因为它们可以捕捉气囊，最小化水滴和物质表面的相互作用。

If it's greater than 90 degrees, then we say that surface is hydrophobic.
