Superhydrophobic and Anti-Icing Coatings on Asphalt Pavements: A Review.

Ice formation on asphalt roads poses severe safety hazards and maintenance issues, especially in cold climates. Traditional deicing methods are typically energy intensive, environmentally adversive, and economically inadvisable. Alternative superhydrophobic coatings (SHCs) have emerged as promising passive anti-icing solutions.

Utilization of SiO Nanoparticles in Developing Superhydrophobic Coatings for Road Construction: A Short Review.

The application of superhydrophobic (SH) coatings in road construction has attracted growing attention due to their potential to improve surface durability, reduce cracking, and enhance skid resistance. Among various materials, SiO nanoparticles have emerged as key components in SH coatings by contributing essential surface roughness and hydrophobicity. This review paper analyzes the role of SiO nanoparticles in enhancing the water-repellent properties of coatings applied to road surfaces, particularly concrete and asphalt.

Structural, surface, and theoretical investigation of hydrophobic-modified nanodiamond powders.

Nanodiamonds (NDs) have received much attention in science and technology due to their superior structural and functional characteristics. In this study, NDs were successfully functionalized with Triethoxy(octyl)silane (TREOS) to make them superhydrophobic. Surface functionalization was carried out through hydrolysis and condensation reactions to create stable Si-O-C and Si-O-Si bonds.

Stearic-Acid-Coated Sand: A Game Changer for Agriculture Water Management.

This study presents the synthesis, characterization, and evaluation of stearic-acid-coated sand (SACS) as a superhydrophobic material for agricultural water management applications. The fabrication process involves coating silica sand particles with stearic acid in an ethanol-based solution, followed by controlled drying to achieve a stable and uniform hydrophobic layer. Structural, chemical, and physical characterizations confirmed the successful functionalization of the sand surface.

Development of Superhydrophobic Reduced Graphene Oxide (rGO) for Potential Applications in Advanced Materials.

Reduced graphene oxide (rGO) was synthesized by chemically reducing graphene oxide (GO) using a reducing agent. The product, rGO, showed excellent hydrophobicity, as indicated by its high-water contact angle, which was greater than 150°. Characterizations using Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, and X-ray diffraction (XRD) were used to analyze the composition and structural differences between GO and the superhydrophobic rGO material.
