“…Comparing with other state-of-the-art coating methods, our method uses only OTS and water to create hierarchical micro/ nanostructure template with low surface tension in a single step, and demonstrates superior wettability and anti-abrasion property (Supplementary Table 3) 6,[8][9][10]43,[46][47][48][49][50][51][52][53] . In comparison, most other strategies relied on the modification of "pre-made" rough structures with low surface tension coatings.…”

Functional and versatile superhydrophobic coatings via stoichiometric silanization

Superhydrophobic coatings have tremendous potential for applications in different fields and have been achieved commonly by increasing nanoscale roughness and lowering surface tension. Limited by the availability of either ideal nano-structural templates or simple fabrication procedures, the search of superhydrophobic coatings that are easy to manufacture and are robust in real-life applications remains challenging for both academia and industry. Herein, we report an unconventional protocol based on a single-step, stoichiometrically controlled reaction of long-chain organosilanes with water, which creates micro- to nano-scale hierarchical siloxane aggregates dispersible in industrial solvents (as the coating mixture). Excellent superhydrophobicity (ultrahigh water contact angle >170° and ultralow sliding angle <1°) has been attained on solid materials of various compositions and dimensions, by simply dipping into or spraying with the coating mixture. It has been demonstrated that these complete waterproof coatings hold excellent properties in terms of cost, scalability, robustness, and particularly the capability of encapsulating other functional materials (e.g. luminescent dyes).

“…The char yield of the CNT/polybenzoxazine composite was as high as 78 wt % at 700 °C. Compared with many other kinds of durable superhydrophobic materials, our CNT/polybenzoxazine coatings are easier to prepare and exhibit remarkable durability against thermal treatment, organic solvents, sandpaper abrasion, and UV irradiation, while retaining their superhydrophobicity (Table 1) [10,11,12,13,16].…”

“…These superhydrophobic surfaces exhibited tremendous resistance against a sandpaper abrasion test and knife scratch. Li and coworkers applied a rapid ultraviolet (UV) cross-linking method to fabricate stretchable surfaces exhibiting excellent superhydrophobicity and self-cleaning ability when encountered with mechanical abrasion and stretching damage [16]. Peng et al synthesized an all-organic superhydrophobic nanocomposite coating that preserved its non-wetting properties under a variety of harshmechanical and chemical environments [17].…”

Superhydrophobic materials have immense applications in the fields of industry and research. However, their durability is still a cause for concern. A facile method for preparing durable superhydrophobic films from carbon nanotubes (CNTs) and the main-chain type polybenzoxazine precursors is reported herein. We used probe ultrasonicator to prepare CNT/polybenzoxazine coatings. Compared with the general sonicating dispersion process, the dispersion time was greatly reduced from a few hours to 5 minutes and the prepared suspension exhibited film-forming characteristics well. The CNT/polybenzoxazine films, which do not contain any fluorinated compounds, exhibit remarkable durability against thermal treatment, organic solvents, corrosive liquids, and sandpaper abrasion, while retaining their superhydrophobicity. Furthermore, these CNT/polybenzoxazine films also showed durable superhydrophobicity after ultraviolet (UV) irradiation for 100 h. This CNT/polybenzoxazine film can be readily used for practical applications to make durable superhydrophobic coatings.

“…In addition, the size can be controlled by adjusting the temperature of hot pressing without the low surface energy material modification. Li et al [131] applied the superhydrophobic PDMS coating to a stretchable double-bonded PUA substrate using a cross-linking method. At the top of the PUA, the superhydrophobic coating was sprayed onto the PUA substrate.…”

Superhydrophobic surfaces (SHS) for underwater drag reduction draw more and more attention owing to its promising and wide applications such as underwater vehicles, pipeline oil transportation, and aquaculture. However, the drag reduction properties are inextricably linked to the stability of air layer on SHS. This review highlights recent advances regarding SHS for underwater drag reduction in the past three years. First, the fundamental theories are briefly described. Next, the crucial influencing factors, which include dimension and arrangement of particles, layout, and shape of the microstructures, Reynolds number, and attack angle on underwater drag reducing performance of SHS are thoroughly listed. Furthermore, the superior or inferior of these manufacturing techniques is also individually illustrated. After that, the solutions of enhancing stability of the air layer are explicitly classified. Then, the practical applications and its potential value in ships and underwater vehicles, microchannels, as well as fabrics are briefly discussed. Finally, the remaining challenges and promising breakthroughs in the field of SHS for underwater drag reduction are clarified in depth.
