A review focused on the superhydrophobic fabrics with functional properties

Abstract

Superhydrophobic (SH) property is a naturally occurring phenomenon that has a wide range of potential applications such as antiicing, anticorrosion, electrowetting, blood typing, and so forth, and therefore, inspires the researchers to mimic them over artificial surfaces to achieve desired properties.Low surface energy and suitable surface roughness are the two key factors that play a vital role in developing SH surfaces. Hence, when the target substrate is introduced with suitable roughness and consequently functionalized with low surface energy, SH can be incorporated. Owing to the SH's wide range of inherent properties such as stain-resistant, self-cleaning, flame retardant, oil/water separation, and so forth as well as tunable functionalities such as electrical conductivity, photocatalytic activity, UV-protection, and so forth, the development of SH fabrics has gained a lot of research attention in recent years. In this context, the present review focuses on the different applications of SH fabrics and their recent research progress.

A facile approach to fabricating fluorine‐free superhydrophobic cotton fabric with excellent oil–water separation performance

“…In recent years, the environmental problems caused by frequent discharges of industrial wastewater and petroleum spill accidents have aroused widespread concerns in recent years 1–3 . Inspired by the unique microstructures of plants and animals such as lotus leaves, rice leaves, water strider legs and butterfly wings, many researchers have developed superhydrophobic materials with water contact angle (WCA) above 150° and water sliding angle (WSA) less than 10° by combining low‐surface‐energy substances with micro/nano rough structures 4–8 . By virtue of special wettability, superhydrophobic porous materials have shown great application potential in the field of oil–water separation and been considered to be the ideal candidates 9–12 .…”

[4][5][6][7][8] By virtue of special wettability, superhydrophobic porous materials have shown great application potential in the field of oil-water separation and been considered to be the ideal candidates. [9][10][11][12] For example, Zhu prepared a superhydrophobic melamine sponge by depositing ferric tetroxide (Fe 3 O 4 ) micro/nano-particles and the coverage of polybenzoxazine.…”

Enhancement of the hydrophobicity and oleophobicity of a polyurethane coating using a fluorine‐free polyfarnesene‐based polyol

“…The wettability of material surfaces is of particular importance in a range of research fields and applications, [1][2][3][4][5][6][7][8] including development of coatings, electronic materials, and biomaterials. Owing to the crucial impact of wettability on material applications, approaches for the development of hydrophobic and oleophobic surfaces have been widely explored.…”
