Fabrication of Superhydrophobic and Oleophobic Thin Films with High Stability and Self-Healing Property

We fabricated the superhydrophobic and oleophobic thin film via layer-by-layer assembling of three kinds of silica nanoparticles and chemical vapor depositing of 1H,1H,2H,2H-perfluorooctyl trichlorosilane (PFTS). The water contact angle of the thin film could reach to 170 degrees, and the contact angle of ethylene glycol was 140 degrees. The thin film could recover the superhydrophobic property after the oxygen plasma treatment. Meanwhile, the thin film could endure the xenon lamp irradiation and water impact experiments.
