Abstract
Superhydrophobic coatings were deposited in modulated RF glow discharges fed with tetrafluorothylene.Such coatings are characterized by a high fluorination degree,ribbon-like randomly distributed surface microstructures,and a certain crystallinity. Combined high fluorination degree and surface texture y roughness leads to the super hydrophobic behaviour,as attested by water contact angle values of 150 8 and more.The coatings were characterized by means of XPS,FT-IR and X-ray diffraction,while time resolved optical emission spectroscopy was utilized to investigate the plasma phase.File in questo prodotto:
