In recent years, both superhydrophilic and superhydrophobic surfaces have undergone much research, as they have enormous potential in many scientific and industrial fields. As part of this final project, we tested superhydrophobicity on stainless and aluminium meshes, which was created by a combination of laser surface treatments and chemical vapor deposition of PDMS with different viscosities. By measuring the contact angle and water flow through the meshes, we proved that the presented hydrophobization process works, that the viscosity of PDMS affects the resulting superhydrophobic film and that by changing the wettability of the meshes it is possible to either increase or completely stop the water flow.
