Advances in the development of superhydrophobic and icephobic surfaces

Abstract

Superhydrophobicity and icephobicity are governed by surface chemistry and surface structure. These two features signify a potential advance in surface engineering and have recently garnered significant attention from the research community. This review aims to simulate further research in the development of superhydrophobic and icephobic surfaces in order to achieve their wide-spread adoption in practical applications. The review begins by establishing the fundamentals of the wetting phenomenon and wettability parameters. This is followed by the recent advances in modeling and simulations of the response of superhydrophobic surfaces to static and dynamic droplets contact and impingement, respectively. In view of their versatility and multifunctionality, a special attention is given to the development of these surfaces using nanocomposites. Furthermore, the review considers advances in icephobicity, its comprehensive characterization and its relation to superhydrophobicity. The review also includes the importance of the use of superhydrophobic surface to combat viral and bacterial contamination that exist in fomites.

Modifications of Textile Materials with Functional Silanes, Liquid Silicone Softeners, and Silicone Rubbers—A Review

“…Different kinds of nanocomposites were also applied for the preparation of hydrophobic and superhydrophobic surfaces. Their use enabled the development of repellent surfaces with antiviral and antibacterial properties and helped to stop pandemics [ 225 ].…”

Superhydrophobic Coating Solutions for Deicing Control in Aircraft

“…In the last 20 years high water-repellent surfaces have attracted the scientific community due to their wide potential applications in various research and technological fields [6,7] (Figure 1). Lotus-leaf-inspired superhydrophobic surfaces (SHS) and Pitcherplant-inspired slippery liquid-infused porous surfaces (SLIPS) are compared in this review work [8] providing the state-of-the-art bio-inspired icephobic coatings/surfaces aimed at aircraft icing mitigation Experiments [9] were carried out at Icing Research Tunnel of Iowa State University (i.e., ISU-IRT) facility aiming to evaluate SHS and SLIPS coatings effectiveness in decreasing or eliminating ice accretion and its impact over the surfaces of typical airfoil/wing models.…”

Superhydrophobic Materials from Waste: Innovative Approach

“…Figure 1. Design of structure and water contact angles and roll-off angles of leaf surfaces with superhydrophobic properties [16,17].…”

“…Superhydrophobic surfaces are typically structured at the micro or nanoscale, featuring a hierarchy of protrusions or textures that minimize the contact area between water and the surface [17]. These intricate surface structures trap air within their interstices, creating a cushioning effect that prevents water from adhering.…”
