Robust and thermally stable hydrophobicity
Researchers report on a robust surface with thermally stable hydrophobicity enabled by electrosprayed fluorinated SiO2 particles.
Highly hydrophobic surface property is important for many applications, such as anticorrosion, antifogging, and antifouling. With regard to some practical applications, both mechanical endurance and thermal stability are essential. Researchers now report a new method for making highly hydrophobic surfaces with simultaneously enhanced mechanical endurance and thermal stability.
Excellent protection effect
These high-performance hydrophobic surfaces were prepared by coating electrospraying derived fluorinated SiO2 particles on various substrates, including glass slide, ceramic wafer, metal foil, and polymer sheet, with methyl silicone resin as the binder. Fluorinate silane was homogenously doped in the matrix of SiO2 particles, which can provide excellent protection effect. Meanwhile, the thermally stable methyl silicone resin can afford strong binding force between SiO2 particles and the substrates.
The study has been published in Journal of Coatings Technology and Research, Volume 19, 2022.
