Fabrication of A Superhydrophobic Surface with Silica Nanoparticles and Polytetrafluoroethylene
Öz
In this paper we fabricate a superhydrophobic surface with Silica nanoparticles and Poly tetrafluoroethylene by using spin coating and microwave plasma treatment on the glass substrate. During the spin coating, the effect of rotation speed on superhydrophobicity is investigated and the optimum rotation speed with high contact angle is identified. It is found that the reaction of PTFE by microwave argon plasma, yields a superhydrophobic surface with contact angle of 163° which is more than the contact angle of the surface without microwave plasma coating. The hydrophobicity of the surface is explained based on Wenzel and Cassie-Baxter regime. The characterization of the rough structure including SiO2 nanoparticle aggregates coated by PTFE is carried out by Scanning Electron Microscopy (SEM), contact angle (CA) by contact angle goniometer with deionized water at room temperature.
