This paper presents the results of the development of a technology to obtain a nanostructured coating for the protection of overhead wires and the possibility of their application in the electric power industry. The paper provides an analysis of available data on methods of combating ice in different countries, ways to protect the surface of metals from environmental influences, and new materials used for protection. We studied the possibility of using a protective nanostructured coating to protect overhead wires. A technology for obtaining a protective nanostructured coating based on silicon oxide and methods for applying it to the wire of overhead lines are proposed. The analysis of the elemental composition and surface morphology of overhead line wires with protective coating is carried out by scanning electron microscopy. The influence of the nanostructured coating on the high-frequency signal bandwidth and wire resistance using a PCIe-6351 data acquisition board, equipped with a BNC-2120 terminal module generating a frequency signal were determined using the National Instruments LabVIEW software package. The subject of the study was a 110 kV overhead power line with a protective coating developed in this work. By analyzing the calculation, we obtained the operating requirements of the developed nanostructured coating. As a result, we developed a protective coating satisfying the working conditions and investigated its properties. In the final phase of the experiment, we tested the electrical characteristics of overhead wires with the developed protective coating.

“…To date, introducing of adhesive resin like polyurethane and polydimethylsiloxane (PDMS) into the coating to protect the hierarchical structure has been proven to be an effective method to improve the mechanical properties of the coating [13][14][15][16][17][18][19][20][21]. Fu et al prepared a fluorine-modified polyurethane through a two-step thiol click reaction, and blended it with silica nanoparticles to prepare a superhydrophobic coating with high mechanical stability.…”

The practical application of superhydrophobic coatings has been greatly restricted due to the complicated preparation and fragile hierarchical structures on the surface. In this study, we prepared a robust superhydrophobic coating with a double-layer structure via a low-cost and facile method, adhering the non-wettability layer composed of silica nanoparticles and fluorine-modified epoxy resin to a binder resin layer on aluminium. The fluorine-modified epoxy resin with low surface energy can fix the silica nanoparticles after curing and cross-link with the adhesive layer. When the SiO2 content in the surface layer is 40%, the water contact angle (WCA) of the coating is 162°, and the sliding angle (SA) is 2°. In the mechanical performance test, the durable coating can remain superhydrophobic even after 260 cycles of friction or 160 cycles of tape peeling. In addition, the superhydrophobic coating with self-cleaning and anti-fouling properties also has the performance of acid-base solution resistance. Hence, the combination of the rough layer and the adhesive layer makes the practical application of artificial superhydrophobic coatings possible.

“…Nano-based superhydrophobic coatings with large water contact angles (CA > 150°) and small water sliding angles (SA < 10°) have also recently attracted significant interest in coating technology as a multifunctional, smarter, efficient, versatile, and durable material . Consequently, various nanocomponents (e.g., natural/synthetic polymers, , inorganic oxides, carbon nanotubes, and clay minerals) were combined with low-surface-energy materials (e.g., natural wax, fluoropolymer, and silicon polymer) to fabricate this special coating. In recent years, increasing environmental concerns have shifted the focus of nano-based superhydrophobic coating science toward bio-based nanomaterials and eco-friendly low-surface-energy materials, such as waxes, fatty acids, proteins, cellulose, biomass, and agricultural waste. , However, to date, most research on nano-based superhydrophobic coatings relies on the use of nondegradable inorganic nanocomponents and fluorine-containing reagents to achieve the required roughness and low surface energy.…”

As a biodegradable and low-cost natural polymer, starch nanoparticles (SNPs) could be used as a substitute for nondegradable inorganic nanoparticles in many advanced materials. However, nano-starch-based superhydrophobic coatings have not yet been reported. Herein, an eco-friendly nano-starch-based superhydrophobic coating was achieved by combining SNPs with poly(dimethylsiloxane). The chemical composition, morphology, superhydrophobicity mechanism, durability, and water resistance of the coating were also investigated. The coating exhibited superhydrophobic properties (water contact angle > 152.0° and sliding angle < 9.0°) owing to the hierarchical micro- and nanostructures formed by SNP aggregates combined with the low surface energy of the PDMS covering. The excellent water resistance, self-cleaning, and liquid-food residue reduction abilities were confirmed. Then, an anthocyanin-rich extract was innovatively loaded into the SNPs to endow the coating with pH responsiveness. Consequently, a waterproof pH-sensing colorimetric coating was successfully developed without the involvement of a chemical reagent for food freshness monitoring. The coating shows great potential in developing advanced eco-friendly food-contact materials to promote the sustainable development of resources in industrial production and daily life.
