Properties of super-hydrophobic copper and stainless steel meshes: Applications in controllable water permeation and organic solvents/water separation

“…The connection between pore sizes of SH meshes and the apparent contact angle has been analyzed mathematically. [2] According to the reformed macroscopic Cassie-Baxter model, the apparent contact angle of SH copper mesh can be given as [2]: The contact angle of smooth copper film surface e was measured to be 51.0° and the contact angle of smooth stainless steel film surface was measured to be 51.1°. The parameters of R and d were determined and are presented in Table 2 and Table 3.…”

“…The self-cleaning ability of natural super-hydrophobic materials such as lotus leaves and butterfly wings have been simulated by artificial super-hydrophobic surfaces with many potential applications [1]. These surfaces have high water contact angle (θ is higher than 150°), low contact angle (CA) hysteresis [2,3] and are produced by combinations of lowering the surface free energy and enhancing the surface roughness [1,2]. Moreover, a super-hydrophobic (SH) mesh has unique characteristics: porous surface, mesh-like geometry, great gas permeation performance, high pressure resistance and high striking loading capacity [4][5][6].…”

Green nanotechnology of trends in future energy: a review

“…Based on the strategies found in nature, bio‐inspired materials will be developed. It is very useful in the design of composite materials, or material structures, which typically offer superior properties and functionality, hierarchical structures, superior assembly mechanisms, superior process control, multifunctionality, and adaptability and hold tremendous potential for improving the capabilities of a wide range of industrial components and systems . Furthermore, mimicking natural material designs and processes is a young and tremendously fertile approach for developing new capabilities and achieving large improvements in existing systems.…”

Superhydrophobic Surfaces by Electrochemical Processes

“…The observation of such phenomena in nature and their understanding allowed to determine two important parameters in order to reproduce superhydrophobic properties: a surface roughness (micro‐ and/or ‐nanostructuration) associated to intrinsically hydrophobic materials at the extreme surface. Indeed, the nature have produced since millennia several plants, insects and animals able to resist to all types of environment and weather using various strategies 1–18. Amongst all these strategies, we can cite the self‐cleaning properties of plants (for examples lotus, candock, rose, silver ragwort, Strelitzia reginae , Asparagus setaceus , Salvinia biloba , Salvinia Molesta , Viola tricolor leaves)1–8 and insects (for example, cicada, moth and termite wings),9–11 insects able to climb on vertical surfaces12 or to walk on water,13 the antireflective and anti‐fogging properties of moth and mosquito eyes respectively,14, 15 the structural color of butterfly wings to push away predators16 and the bactericidal properties of cicada wings ( Figure and ) 17…”
