Preparation of superhydrophobic surface with tunable adhesion on glass substrate

Superhydrophobic coatings help to reduce the surface contamination of glass and improve its performance. A SiO₂ nanoparticles superhydrophobic surface with tunable adhesion is obtained on a glass substrate after modifying with PDMS. With the water contact angle of 155.1 ± 3°, the superhydrophobic surface also shows excellent self-cleaning property, good durability and thermal stability. This method is facile, cost-effective and easy to operate and will expand the potential applications of glass materials in different fields. (paper)
