Abstract
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.
Highlights
The wettability of surfaces is one of the most important characteristics of solid surfaces [1]
Zhan et al [89] proposed an anti-icing hybrid material with a high static water contact angle (WCA) of 170.3◦ and a low contact angle hysteresis (CAH) of less than 3◦ synthesized by grafting fluorinated polymer chains to silica nanoparticles via surface-initiated activators generated by electron transfer atom transfer radical polymerization (SI-AGET ATRP)
Duetototheir theirspecific specificproperties, properties,including includingself-cleaning, self-cleaning,antiantifogging, corrosion resistance, anti-icing and icephobic properties, the fields fogging,drag-reduction, drag-reduction, corrosion resistance, anti-icing and icephobic properties, the offields theirofapplication are expected to expand in the future
