“…Anodization is a process that makes structures with huge nanopore arrays on metallic substrates with alterable shape, size, and morphology. An anodization technique has been widely used to prepare versatile nanostructures through the control of temperature, electrolytes, and an applied voltage [147][148][149][150]. Liang et al [151] prepared a superhydrophobic Ti surface by using single-step anodization and fluorination.…”

Superhydrophobic surfaces are found in nature and possess several fascinating properties, including the ability to self-clean. A typical superhydrophobic surface has micro/nanostructure roughness and low surface energy, which combine to give it its unusual anti-wetting properties. Because of their unique capabilities, these surfaces have interested scientists in research and industry fields for years. In recent decades, researchers have developed a number of synthetic methods for producing novel superhydrophobic surfaces that mimic natural surfaces. These synthetic surfaces have been widely applied on different types of substrates for potential widespread, practical applications. This review article focuses on these advances in fabricating manmade superhydrophobic surfaces.

“…The general process for preparing a superhydrophobic surface is the construction of surface roughness and modification with low-surface-energy coatings [8]. Widely used methods for the surface modification of materials include radiation grafting, [9,10,11], electrospinning [12], sol-gel method [13,14], magnetron sputtering [15,16,17], self-assembly [18], and vacuum thermal evaporation. Kim et al [19] synthesized fluorosilicone copolymers by free-radical random copolymerization using fluorine-containing monomers and silicon-containing monomers as raw materials to improve the hydrophobicity of PVC and increase the apparent water contact angle (AWCA) [20,21] of PVC to 117°.…”

Wind power generation is an environmentally friendly way to produce electricity, but wind turbine blades that are prone to freeze in winter will reduce the efficiency of the generator. Therefore, the preparation of anti-icing blades is important and essential. Herein, anti-icing polytetrafluoroethylene (PTFE)/heat-shrinkable polyvinyl chloride (HSPVC) composite film was prepared by depositing a PTFE coating on the surface of HSPVC film via vacuum thermal evaporation. HSPVC films were pretreated respectively by argon and carbon tetrafluoride (CF4) plasma cleaning to introduce new groups and change their surface energy. After that, PTFE coating with a thickness of about 4 μm was deposited on the surface of HSPVC, obtaining a superhydrophobic surface with an apparent water contact angle of 150°. The results demonstrated that the breaking strength of the PTFE/HSPVC composite film using CF4 plasma pretreatment decreased by only 3.47% after exposing to ultraviolet light with the power of 1000 W for 5 min, suggesting an excellent anti-ultraviolet property. Furthermore, compared with the pristine films, the PTFE/HSPVC composite films exhibited better adhesive strength, super anti-icing property even after 10 icing–deicing cycles, and excellent dynamic anti-icing performance. The PTFE/HSPVC composite film with good adhesive strength, anti-ultraviolet, and anti-icing properties has prospective applications in packaging of wind turbine blades.

“…Polytetrafluoroethylene (PTFE) is very well‐established commercial material in the field of anti‐reflecting as well as superhydrophobic materials research due to its very low surface energy (≈18.6 mN m −2 ), low refractive index (RI) of ≈1.38, high thermal and chemical stability, etc . These excellent properties make the material very useful for outdoor applications.…”

Superhydrophobic (water contact angle ≈168° and sliding angle ≈1°) and ultra‐wideband (entire visible to near infrared, i.e., 400–1100 nm), omnidirectional (0–60°) anti‐reflecting (Tmax ≈98% and Tavg ≈97%) polytetrafluoroethylene (PTFE) coatings are fabricated in a rapid single step deposition process by electron beam evaporation technique. The methodology followed in this work avoids conventional complicated multistep chemical processes and reduces the deposition time to ≈3 s. This novel coating strategy may be of potential use in fabricating highly transparent multifunctional optical coatings on glass cover panels with excellent self‐cleaning property for various outdoor applications.
