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°, and the contact angle of ethylene glycol was 140°. 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.
