This property describes a surface’s ability to repel water.
For highly hydrophobic materials, the repellent behavior reaches impressive levels. For instance, lotus leaves are so famous for their water repulsiveness that a material with a surface extremely difficult to wet is said to produce a Lotus effect.
For these materials, the term superhydrophobic is even used. Lotus leaves, which allow water to flow without getting wet, is similar to milkweed fibres; the angle of contact between its surface and a droplet is very high (as shown below), preventing water from clinging.
