Superhydrophobic coatings in 2026: overview

Superhydrophobic coatings combine a textured surface with low surface energy to repel water. This can support self-cleaning, corrosion protection and reduced ice adhesion, but the structures that create water repellency can also wear or lose function under abrasion and harsh exposure. Current work therefore focuses on durability alongside repellency, while adding functions such as photothermal heating, self-healing and corrosion resistance.

Recent studies show that direction clearly. In October 2026, South China University of Technology reported a fluorine-free, ultra-slippery coating made by one-step calcination of UiO-66@PDMS; other work combined dual resins to balance wetting control and mechanical durability. September 2026 publications explored photothermal anti-icing through Fe3O4–CuS@C and introduced an argon gas film to improve performance in cold, humid conditions. Research is also moving toward repairable and recyclable materials, including self-healing graphene-oxide coatings and coatings made with recycled wind-turbine blade powder.

  • 1Durability is central: Mechanical robustness is becoming a design requirement: researchers are trying to preserve water repellency after wear, damage and exposure to demanding environments.
  • 2Active ice control: Photothermal coatings pair passive water repellency with sunlight-driven heating, aiming to address the limits of superhydrophobicity alone in anti-icing and de-icing.
  • 3Fluorine-free options: Work on fluorine-free formulations and recycled feedstocks signals a shift toward coatings that combine performance with more sustainable material choices.
