Fabrication and color-gradient control of colorful superhydrophobic materials with mechanical durable, oil/water separation and recyclable properties

On the Development of Ultradurable Extremely Water-Repellent and Oleophobic Soot-Based Fabrics with Direct Relevance to Sperm Cryopreservation

“…The evaluation of mechanical flexibility, scratching and cutting robustness, thermal shock- and fire resistance, jetting endurance and adhesion strength of the soot fabrics involved a few well-established control tests. , All samples were subjected to abrasive wear by rubbing them to the surface of a P1200 sandpaper under an applied load of 200 g, analogously to foregoing studies. , Then, the surface adhesion was analyzed via an ASTM D3359 standard tape test, while the underwater stability was estimated by high-velocity (∼25 m/s) water jetting. The soot patterns were also manually crumpled, hit by 200 g steel weights, submerged in liquid nitrogen for 10 s, exposed to a butane flame for 5 s, and scraped by a knife, and their wetting state was verified by impacting tap water droplets.…”

From Extremely Water-Repellent Coatings to Passive Icing Protection—Principles, Limitations and Innovative Application Aspects

“…Therefore, the attention of both scientists and funding agencies gradually shifts towards a relatively new concept (intensively explored for about a decade) for passive icing protection, namely using superhydrophobic coatings. The latter are prone to fair criticism, because of their fragility and lack of scalability [71], but these significant drawbacks seem to steadily being overcome and many researchers report on the fabrication of scalable, robust and wear-resistant water repellent materials [72][73][74][75][76].…”

Aqueous Fabrication of Recyclable and Color-Adjustable Superhydrophobic Pigments Based on NiFe-Layered Double Hydroxide Nanostructures for Coating Applications

“…13 Although the structural color is physical color and only relates to the surface structure, it is prone to fade due to structural damage and its preparation process is also complicated, so it is not suitable for color display of architectural coating and artworks. 17,18 The second method relies on coloring materials, namely, nanofillers colorized by commercial organic dyes and inorganic pigments with inherent colors. 4,5,17−23 Ren et al constructed SHP coatings with abundant colors via dying nanoparticles with three commercial organic dyes, followed by hydrophobic modification with fluorinated long-chain silane.…”

“…Structural colors shone out by the interaction between the submicron structure of the material surface with visible light, like interference, scattering, and diffraction. − Yi et al designed an SHP structure colorful film via polydopamine-coated polystyrene (PS@PDA) nanoparticles to form a structural color, which was then dip-coated with polydimethylsiloxane solution for waterproofing purposes . Although the structural color is physical color and only relates to the surface structure, it is prone to fade due to structural damage and its preparation process is also complicated, so it is not suitable for color display of architectural coating and artworks. , …”
