A simple and easy method to prepare super-hydrophobic surface was proposed. Sol-gel films were prepared by hydrolysis and condensation of alkoxysilane compounds. The roughness and free energy at the film surface were controlled by changing the amounts of colloidal silica particles and fluoroalkylsilane, respectively. When both amounts were optimized in a sol-gel film, the surface exhibited an excellent repellency to not only water but also oil. The sol-gel film obtained could be coated onto any solid substrate by a single process. The durability and transparency of the coated layers were sufficient to be applied for practical uses.
