Super-hydrophobic surfaces, with a water contact angle(CA) greater than 150 degrees, have attracted much interest for both fundamental research and practical applications such as nonstick cookware, windmills, water-resistant boat materials and marine structures. Here we have produced super-hydrophobic surface using hybrid sepiolite, which has been modified by fluorosilica. Sepiolite presented nano tube like morphology and its treatments with fluorosilica reduce surface energy, increasing its hydrophobic properties. The combined effect of low surface energy and controlled surface roughness resulted in high advancing contact angles and low contact angle hysteresis. In addition, we also characterized mechanical properties of the hybrids coating materials. Contact angle(CA), Scanning Electron Microscope(SEM), Atomic Force Microscope (AFM) and X-ray Photoelectron Spectroscopy(XPS) were used to characterize the super-hydrophobic surface. |
