“…For marine vessels, the frictional resistance from the water accounts for approximately 80% of the total resistive force consisting of frictional drag and pressure drag [28,29]. The drag-reduction property of superhydrophobic coatings can reduce the frictional resistance and thus increase the moving speed, cutting down fuel consumption and CO 2 emission.…”

With the development of material engineering and coating industries, superhydrophobic coatings with exceptional water repellence have increasingly come into researchers’ horizons. The superhydrophobic coatings with corrosion resistance, self-cleaning, anti-fogging, drag-reduction, anti-icing properties, etc., meet the featured requirements from different application fields. In addition, endowing superhydrophobic coatings with essential performance conformities, such as transparency, UV resistance, anti-reflection, water-penetration resistance, thermal insulation, flame retardancy, etc. plays a remarkable role in broadening their application scope. Various superhydrophobic coatings were fabricated by diverse technologies resulting from the fundamental demands of different fields. Most past reviews, however, provided only limited information, and lacked detailed classification and presentation on the application of superhydrophobic coatings in different sectors. In the current review, we will highlight the recent progresses on superhydrophobic coatings in automobile, marine, aircraft, solar energy and architecture-buildings fields, and discuss the requirement of prominent functionalities and performance conformities in these vital fields. Poor durability of superhydrophobic coating remains a practical challenge that needs to be addressed through real-world application. This review serves as a good reference source and provides insight into the design and optimization of superhydrophobic coatings for different applications.

“…If the frictional resistance can be reduced by 10%, the speed and voyage of the ships would increase by 3.57%. 2,3 Therefore, reducing surface frictional resistance is of great signicance in practical engineering applications such as ships, underwater detectors, submarines, and torpedoes. 4 The current methods of uid drag reduction mainly include microbubble, 5 polymer additive, 6 superhydrophobic 7 and bionic structure 8 methods.…”

“…For vessels with slower sailing speeds, the frictional drag experienced is 80% of the total drag. [ 1 ] Friction drag accounts for nearly 50% of the total drag during flight for a large transport plane and even more for a smaller civil aircraft. [ 2 ] In fact, it is estimated that an A340‐300 aircraft will save about 400 000 L of fuel per year by just 1% drag reduction.…”

After a long period of biological evolution, natural creatures will inevitably evolve body surfaces suitable for the living environment. The functions of natural biological surfaces are abundant and powerful, including antiadhesion, self‐cleaning, drag reduction, anti‐icing, wear resistance, and other characteristics. In the context of coping with the energy crisis, inspired by natural biological surface microstructures, researchers explore biomimetic surface microstructures that reduce fluid drag and investigate the mechanisms of drag reduction. Herein, mainly the current state of research on biomimetic textured surfaces that can be applied to fluid drag reduction is reviewed and the microstructures’ morphology, drag reduction mechanisms, and the fabrication techniques of textured surfaces are discussed in detail. In particular, the experimental methods for measuring the drag reduction effect of textured surfaces are introduced, which is extremely rare. The article concludes with a summary of existing problems and future directions in the research of biomimetic surface drag reduction technology. This Review can provide a reference for practical application and laboratory research of drag reduction in marine transportation, military weapons, aviation, and pipeline systems.
