Microfabrication of polymeric surfaces with extreme wettability using hot embossing

Droplet Impact on the Super-Hydrophobic Surface with Micro-Pillar Arrays Fabricated by Hybrid Laser Ablation and Silanization Process

“…Inspired by natural lotus leaves [2], rose petals [3], and butterfly wings [4], super-hydrophobic surfaces (i.e., apparent contact angle above 150° and sliding angle below 10°) have been successfully mimicked through the synergetic effects of micro/nanostructure fabrication and surface chemical modification [5,6,7,8,9,10]. Due to their enormous potential applications including anti-icing [11], drag reduction [12], self-cleaning [13], anti-bacteria [14], and corrosion resistance [15], super-hydrophobic surface mimicry has been extensively developed by state-of-the-art techniques, such as thermal imprinting [16,17], chemical vapor deposition [18], coating [19], electrochemical deposition [20,21], and laser texturing [22,23,24,25,26,27]. Particularly, laser texturing can be seen as one of the facile approaches, and therefore can be extensively utilized to fabricate super-hydrophobic substrates owing to its precise control of surface fabrication with three dimensional (3D) hierarchical structures [28].…”

SiO2 Nanoparticles Modified by Bridged Polysilsesquioxane-Based Protective Coatings for Moisture Proofing and Antireflection Applications

“…Second the single layer approach which realizes the moisture-proof and AR performance in accordance with the hydrophobic and porous structure of the coating. Various methods have been exploited toward hydrophobicity modification, , such as template methods, phase separation methods, self-assembly methods, and so on. For instance, Ye et al developed a class of superhydrophobic surfaces with hydrophobic SiO 2 nanoparticles (NPs).…”

Nonwet Kingfisher Flying in the Rain: The Tumble of Droplets on Moving Oriented Anisotropic Superhydrophobic Substrates

“…Therefore, the water-repellent mechanism of the coupling between anisotropic hydrophobic feathers and the movement before takeoff or during flight may be beneficial to the reduction of any negative effects caused by added moisture mass, such as diminished aerodynamic performance. So far, many studies have only explored the bionic manufacture and wetting of stationary substrates [12][13][14][15][16][17][18][19][20][21] , but obviously, the dewetting previously described processes all occur on birds' moving exteriors, as they are movable.…”
