Web16 Apr 2015 · Ultrahydrophobic surfaces are based on the lotus effect, discovered in the seventies through the microscopic observation of the natural hydrophobic properties of … Web17 Nov 2009 · However, no existing theories of surface wetting can provide guidance to pinpoint the texture size requirement to achieve super/ultrahydrophobicity. Here, we show that the three-phase contact line tension, tau, is an important link to understand the dependence of macroscopic wetting on physical texture size in an ideal Cassie regime.

The Lotus Effect. Living in a pond, Survival depends on one’s —. Water repellence. The trick to living as a lotus leaf is to be on (or when possible … Ultrahydrophobic (or superhydrophobic) surfaces are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet on an ultrahydrophobic material exceed 150°. This is also referred to as the lotus effect, after the superhydrophobic leaves of the lotus plant. A droplet … See more In 1805, Thomas Young defined the contact angle θ by analysing the forces acting on a fluid droplet resting on a smooth solid surface surrounded by a gas. where See more Many very hydrophobic materials found in nature rely on Cassie's law and are biphasic on the submicrometer level.
