Recent Advances on the Abrasion Resistance Enhancements and Applications of Superhydrophobic Materials

Abstract

Researches on superhydrophobicity have been overwhelming and have shown great advantages in various fields. However, the abrasion resistance of superhydrophobic structures was usually poor, and they were easily damaged by external force or harsh environment, which greatly limited the applications of superhydrophobic surfaces. Much attention has been paid to improving the abrasion resistance of superhydrophobic materials by researchers. In this review, aimed at the advances on improving the abrasion resistance of superhydrophobic surfaces, it was summarized and compared three enhancement strategies including the reasonably design of micro‐nano structures, the adoption of adhesives, and the preparation of self‐healing surface. Finally, the applications of typical superhydrophobic materials with abrasion resistance were reviewed in various fields. In order to broaden the application fields of superhydrophobic materials, the abarasion resistance should be further improved. Therefore, we proposed the ideas for the future development of superhydrophobic materials with higher abrasion resistance. We hope that this review will provide a new approach to the preparation and development of stable superhydrophobic surfaces with higher abrasion resistance.

Preparation of superhydrophobic asymmetric vitrimer coating with high porosity and the key role of hierarchical pocket structure on long freeze delay time and high durability

“…), which is a major barrier for practical applications. 15,16 Tuukka Verho points out mechanical contact not only causes damage to roughness patterns but also surface contamination, which shortens the lifetime of superhydrophobic coating and anti-icing performance. 17 Besides, Dimos Poulikakosa indicates that high-speed liquid droplet/jet impacting a trigger thermodynamic instability of superhydrophobic coating via cushions removal induced Cassie-Baxter to Wenzel transition, which sometimes lead to the loss of liquid repellence.…”

“…Apart from the previously mentioned issue, superhydrophobic coatings rapidly lose their capacity to repel water when subjected to physical force (such as rubbing, hitting, etc. ), which is a major barrier for practical applications 15,16 . Tuukka Verho points out mechanical contact not only causes damage to roughness patterns but also surface contamination, which shortens the lifetime of superhydrophobic coating and anti‐icing performance 17 .…”

A Superhydrophobic Coating with Sturdy Abrasion and Weather Resistance

“…With respect to the fabrication of the superhydrophobic coatings, the common points are the combination of the rough surface textures with the hydrophobic substrate layers. Over the past few years, a rapidly-growing quantity of superhydrophobic coatings has been reported [11,12]. Nonetheless, these existing and ongoing endeavors do not necessarily lead to valuable applications, given the fact that most of these paradigms do not purposefully aim at practical applications and especially outdoor applications which typically require anti-ultraviolet properties, strong wear and corrosion resistance, besides the superhydrophobic ability.…”

Synthesis of reticular long-carbon-chain polysiloxane and its hydrophobic modification of phosphogypsum-based materials

“…The preparation of high-strength and high-wear-resistance surface hydrophobic coatings remains a challenge. 14,15 Polysiloxanes can not only be used to prepare surface hydrophobic coatings but also impart overall hydrophobicity to phosphogypsum-based materials by internal mixing. Chen et al 16 prepared flue-gas desulfurization gypsum blocks using polymethyl hydrosiloxane as a waterproofing and weatherproofing agent and fly ash as a mineral admixture.…”
