Superhydrophobic ice-phobic zinc surfaces

The synthesis process of superhydrophobic metal surfaces and their anti-icing properties is presented. The anti-icing and superhydrophobic behavior was studied, and durability tests showed good performance of the surfaces.

Galvanizing steel is widely used in many industrial sectors to create a protective layer against corrosion and environmental attacks, but it faces issues with wetting and ice formation.

 

This study introduces a simple and scalable process to achieve superhydrophobic and ice-phobic zinc surfaces, prepared by growing ZnO nanorods in a brief hydrothermal treatment (<30′) at 90°C. Further coating with stearic acid or fluoroalkylsilane results in surfaces with static contact angles exceeding 165° and tilt angles up to 1°. A clear correlation between wettability and ice adhesion was found, demonstrating excellent ice-phobic performance for all superhydrophobic samples with shear stress values below 10 kPa. Durability was evaluated, and samples retained some of their properties after 30 days of immersion in humid chemicals. An easy recovery process can further enhance the ice-phobicity of the samples.
