Special Issue Information

Dear Colleagues,

This Special Issue of Coatings explores the significance of hydrophobic surfaces, texturing techniques, and coatings in tribology, materials science, and surface engineering. Hydrophobic surfaces have immense potential across various industries. They enhance aerospace efficiency, improve energy production, and prevent infections in medical devices. Surface texturing, achieved through laser ablation and chemical etching, complements hydrophobicity by introducing self-cleaning and anti-fogging properties. Advanced coatings, composed of specialized polymers or nanoparticles, further enhance hydrophobicity and find applications in automotive and marine industries.

This Special Issue showcases the latest research in this field, highlighting its essential role in shaping future science and technology. It anticipates ground-breaking insights and applications to drive progress toward a more sustainable and technologically advanced world. Original research articles and reviews are welcome. Research areas may include, but are not limited to:

  1. Advanced surface engineering methods for creating hydrophobic surfaces;
  2. Nanotechnology and nanomaterials applications in hydrophobic coatings and surface texturing;
  3. Biomedical applications to expand the use of hydrophobic surfaces and coatings in the medical field;
  4. Environmental Impact and implications of hydrophobic materials and coatings;
  5. Hydrophobic surfaces in energy production, storage, and transportation;
  6. Integration of hydrophobic technologies with smart surfaces and sensors;
  7. Tribology of hydrophobic surfaces and coatings;
  8. Electrochemistry for micro and nanostructuring of hydrophobic surfaces.

We look forward to receiving your contributions!

Controlling the wettability properties of metallic materials and surfaces can enhance their applicability and improve their performance and durability in several fields, such as corrosion protection, heat transfer applications, self-cleaning, and friction reduction. Here, we present and compare some versatile fabrication methods that can provide aluminum surfaces with durable superhydrophobic performance which are suitable for heat transfer applications. To probe their stability in heat transfer applications, two evaluation protocols are designed, one which suggests immersion in hot water for several hours, and a second testing against the harsh conditions of hot steam impact. The superhydrophobic aluminum surfaces are fabricated by first creating micro or micro-nano roughness on an initially flat surface, followed by the minimization of its surface energy through two hydrophobization methods, one wet and one dry, thus creating a series of different coating materials. Surfaces are then evaluated by immersing them in hot water and exposing them to steam impact. It is demonstrated that despite the fact that all hydrophobization methods tested resulted in surfaces exhibiting superhydrophobic properties, only the ultra-thin Teflon-like coating, obtained after plasma deposition using C4F8 plasma, exhibited robust superhydrophobicity with hysteresis lower than 8° when immersed in water at 90 °C for 10 h. This surface also showed minimal wettability changes and was the only one to retain its hysteresis below 6° after 4 h of exposure to hot steam. Full article
