Ultrahydrophobicity - Wikipedia
In chemistry and materials science, 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°. [1] This is also referred to as the lotus effect, after the superhydrophobic leaves of the lotus plant.
Superhydrophobic coating - Wikipedia
A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of …
Design of robust superhydrophobic surfaces | Nature
2020年6月3日 · Here we show that robust superhydrophobicity can be realized by structuring surfaces at two different length scales, with a nanostructure design to provide water repellency and a microstructure...
Superhydrophobic - an overview | ScienceDirect Topics
Superhydrophobic surfaces are surfaces with high water contact angles and low surface energy, allowing water droplets to roll off extremely easily due to lower contact angle hysteresis.
Review on Superhydrophobic Polymer Composite Coating …
2024年12月17日 · Superhydrophobic surfaces repel water primarily due to their surface texture and physicochemical properties. The present article deals with the basic and fundamental principles, importance and applications of superhydrophobic behavior of materials, including different analytical and fabrication techniques used to study and to ascertain the ...
Superhydrophobic surfaces: from structural control to functional ...
In this feature article, we review the historical and present research on superhydrophobic surfaces, including the characterization of superhydrophobicity, different ways to fabricate rough surfaces, and low-surface-energy modifications on inorganic and organic rough surfaces.
Superhydrophobic surfaces - ScienceDirect
2006年10月1日 · Non-wettable surfaces with high water contact angles (WCAs) and facile sliding of drops, called superhydrophobic or ultrahydrophobic, have received tremendous attention in recent years.
Superhydrophobic Natural and Artificial Surfaces—A Structural …
Superhydrophobic surfaces which display a contact angle higher than 150°, or 180°, (according to other authors) and a sliding angle smaller than 10° attracted attention of researchers. They were first observed in the natural environment (Lotus leave, butterfly wings, fish scales etc.).
Superhydrophobic Surfaces & Underwater Longevity
A submerged surface can only remain superhydrophobic (SHP) as long as it retains the trapped air in its pores. SHP surfaces have a short underwater life, and their longevity depends strongly on the hydrostatic pressure at which they operate.
Superhydrophobic and superoleophobic properties in nature
2015年6月1日 · In this review, we report on superhydrophobic and superoleophobic properties found in nature, which are strongly expected to benefit various potential applications.
