Progess in superhydrophobic surface development

Nano-scale superhydrophobicity: suppression of protein adsorption and promotion of flow-induced detachment

“…A large number of techniques have been developed to produce different superhydrophobic surfaces for study 4 , a small number have been developed into products. 5,6 Protein adsorption is the first stage in biological contamination of surfaces, with cells binding to a pre-adsorbed protein layer before proliferating and spreading.…”

A facile dip-coating process for preparing highly durable superhydrophobic surface with multi-scale structures on paint films

“…Although the untreated M1 surface displays a high contact angle (154°), the sliding angle as high as 90°is found on this surface. This phenomenon implies water has a very strong interaction with the surface, and hence it is more close to ''Wenzel" regime [31], attributing to the relative hydrophilic property of the epoxy resin. After dip-coating with M2 solution, the surface showed a dramatically reduced sliding angle of $60°at 0.05% of ATPS concentration, and then it further jumped to 10°at 0.1%.…”

“…Although great successes have been made in the preparation of such structures, and superhydrophobic surfaces with an apparent contact angle close to 180°have been prepared from many different techniques [13,31], the successful applications of these manmade superhydrophobic surface are still at the premature stage, mainly due to the lack of facile ways for large scale fabrication and insufficient durability of the prepared superhydrophobic structures [32][33][34][35][36][37]. For example, many superhydrophobic surface are directly built up on metal surfaces [16][17][18][19][20][21], which are not stable in the conditions for many of above mentioned applications because these condition are usually corrosive to metal and can easily destroy the superhydrophobic structures.…”

External‐Field‐Induced Gradient Wetting for Controllable Liquid Transport: From Movement on the Surface to Penetration into the Surface

“…[1][2][3][4][5][6][7][8] The liquid-wetting behavior on a solid or liquid surface is mainly dependent on the chemical composition and surface roughness, which play important roles in liquid transport. [9][10][11][12][13][14][15][16] The wettability gradient of a surface for a liquid droplet with an asymmetrical contact angle (CA) can produce a driving force for liquid motion, which is generally generated by introducing a chemical or structure gradient. [17][18][19][20][21][22][23][24][25][26][27][28] External-field-responsive liquid transport has received extensive research interest owing to its important applications in microfluidic devices, biological medical, liquid printing, separation, and so forth.…”
