BIOMIMETIC SUPERHYDROPHOBIC SURFACES

2014
Inspiration from nature has been widely used in the development of new materials and in the improvement of their properties. Superhydrophobic surfaces inspired in species present in nature with highly water repellent self-cleaning properties — such as the well-known lotus leaf — are interesting examples of the biomimetic approach for the development of

Patterned Superhydrophobic Metallic Surfaces

Langmuir, 2009
This work shows that after creating certain dual scale roughness structures by femtosecond laser irradiation different metal alloys initially show superhydrophilic behavior with complete wetting of the structured surface. However, over time, these surfaces become nearly superhydrophobic with contact angles in the vicinity of 150 degrees and ...

Electrokinetics on superhydrophobic surfaces

Journal of Physics: Condensed Matter, 2012
On a superhydrophobic surface a liquid is exposed to a large air-water interface. The reduced wall friction is expected to cause a higher electro-osmotic mobility. On the other hand, the low charge density of a superhydrophobic surface reduces the electro-osmotic mobility.

Superhydrophobic Hierarchical Honeycomb Surfaces

Langmuir, 2012
Two-dimensional hexagonally ordered honeycomb surfaces have been created by solvent casting polybutadiene films under controlled humidity. Subsequent CF(4) plasmachemical fluorination introduces cross-linking and surface texturing, leading to hierarchical surfaces with roughness on both the 10 μm (honeycomb) and micrometer (texturing) length scales ...

Superhydrophobic Metal Surface

2021
Demands of metals in automobiles, construction, aerospace, and other applications have increased because of their texture, strength, and flexibility; however, undesired corrosion makes their applications limited to a certain period. Although several methods like painting, cathodic deposition, and the creation of alloys have been developed in the recent

Superhydrophobic Surfaces by Electrochemical Processes

Advanced Materials, 2013
AbstractThis review is an exhaustive representation of the electrochemical processes reported in the literature to produce superhydrophobic surfaces. Due to the intensive demand in the elaboration of superhydrophobic materials using low‐cost, reproducible and fast methods, the use of strategies based on electrochemical processes have exponentially ...

Nanostructured superhydrophobic surfaces

Journal of Materials Science, 2005
A study on superhydrophobic silica surfaces based on roughness created by assembling different nanostructured materials was reported. Four different surface structures were created on a silica base material, which was subsequently covered with a self-assembled monolayer of tridecafluoro-1,1,2,2- tetrahydrooctyldimethylchlorosilane (TFCS).

Biomimetic Superhydrophobic Surfaces

Journal of Dispersion Science and Technology, 2013
Lotus leaves are well known to be superhydrophobic and self-cleaning due to the hierarchical roughness of the leaf surfaces. The surfaces with controllable wettability may bring great advantages in a wide variety of applications and have received tremendous attention in recent years.

Sticky superhydrophobic surface

Applied Physics Letters, 2007
The authors present a simple and inexpensive method for fabricating a stable superhydrophobic engineering material surface using aluminum alloy and a suitable aqueous solution and time to control the surface roughness, which has a large water contact angle (>150°) and a large water sliding angle (>90°).
