  The synthesis and texturization processes of fluorinated surfaces by means of
atmospheric plasma are investigated and presented through an integrated study
of both the plasma phase and the resulting material surface. Three methods
enhancing the surface hydrophobicity up to the production of super-hydrophobic
surfaces are evaluated: (i) the modification of a polytetrafluoroethylene
(PTFE) surface, (ii) the plasma deposition of fluorinated coatings and (iii)
the incorporation of nanoparticles into those fluorinated films. In all the
approaches, the nature of the plasma gas appears to be a crucial parameter for
the desired property. Although a higher etching of the PTFE surface can be
obtained with a pure helium plasma, the texturization can only be created if O2
is added to the plasma, which simultaneously decreases the total etching. The
deposition of CxFy films by a dielectric barrier discharge leads to hydrophobic
coatings with water contact angles (WCAs) of 115{\textdegree}, but only the
filamentary argon discharge induces higher WCAs. Finally, nanoparticles were
deposited under the fluorinated layer to increase the surface roughness and
therefore produce super-hydrophobic hybrid coatings characterized by the
nonadherence of the water droplet at the surface.
