Recent experiments have revealed that the wax on the lotus leaf surface, by itself, is weakly hydrophilic, even though the lotus leaf is known to be superhydrophobic. Conventional understanding suggests that a surface of such waxy composition should not be able to support superhydrophobicity and high contact angles between a liquid and the surface. Here, we show that the unexpected superhydrophobicity is related to the presence of “reentrant texture” (that is, a multivalued surface topography…

Outmatching superhydrophobicity: bio-inspired re-entrant curvature for mighty superamphiphobicity in air

Understanding the complementary roles of surface roughness and energy in natural super-non-wetting surfaces has greatly promoted the development of biomimetic superhydrophobic surfaces that repel

A superamphiphobic macroporous silicone monolith with marshmallow-like flexibility.

The first superamphiphobic monolith is prepared using marshmallow-like gels derived from triand difunctional alkoxysilanes as coprecursors through a facile one-pot sol–gel reaction, which has high porosity, flexibility both for compression and bending, and built-in superhydrophobicity.

Superomniphobic surfaces: Design and durability

Surfaces that display liquid contact angles greater than 150° along with low contact angle hysteresis for liquids with both high and low surface tension values are known as superomniphobic surfaces.
