Mechanically robust, thermally stable, highly transparent superhydrophobic coating with low-temperature sol–gel process

Abstract

The wetting behavior of transparent superhydrophobic surfaces has attracted much attention in our daily life as well as in engineering applications.

Smart Nanocoating (Metal oxide and Composite) and its surface functionalization for Environmental Remediation

“…Zhang et al have developed optically transparent superhydrophobic SiO 2 films which were synthesized by sol-gel method. Comparing with the 1, 1, 1, 3, 3, 3hexamethyldisilazane (HMDS)-modified films (140 AE 2 ), the films modified by trimethylchlorosilane (TMCS) showed very high water contact angle (164 AE 2 ), which indicates the excellent waterproof behavior of the films (Zhang et al 2017b). S. G. Lee et al have developed the SiO 2 -fluoropolymer hybrid nanoparticles (SFNs) on coated steel substrate by the spray-coating process.…”

Graphene tailored by Fe3O4 nanoparticles: low-adhesive and durable superhydrophobic coatings

“…As we know, super-hydrophobic surfaces are easy to lose the super-hydrophobicity under high temperature and humidity, because surface chemical groups '-X' would be oxidized/ hydroxylated to -OH groups, leading to the adsorption of water. 63 And changes in the surface morphology under high temperature might weaken the surface hydrophobicity. We thus examined the thermal resistance of superhydrophobic Fe 3 O 4 / FLG hybrid coating with 1.8 g Fe 3 O 4 (i.e., Fe 3 O 4 -1.8) which shows the best water-shielding ability.…”

The Synthesis of a Superhydrophobic and Thermal Stable Silica Coating via Sol-Gel Process

“…For these superhydrophobic coatings to be implemented to industry, they must be easily fabricated and durable during services. However, many superhydrophobic coating materials deteriorate at relatively low temperatures, 300-350 • C, due to raw materials' low thermal stabilities, giving rise to a surface morphology or chemistry damage of the coatings surface [21][22][23].…”
