This works presents the development of plasma-polymrized surfaces for superhydrophobic, gas barrier and UV attenuation properties. These functional coatings have been deposited by means of atmospheric pressure dielectric barrier discharge (DBD). The first part deals on the plasma polymerization of the de 1H, 1H, 2H, 2H, Perfluorodecyl acrylate. According to the plasma parameters, surperhydrophobic coatings have obtained on several substrates. Morphologies analysis have shown the formation of fluorinate nanoparticles. The second part of the work was to develop gas barrier films from hexamethyldisiloxane. Thus, SiOx thin films and SiOxHyCz / SiOx multilayers have been obtained in order to improve the barrier performance of PET and PEN substrate. Finally, obtaining UV barrier film was to an in-situ growth of nanoparticles of titanium (TiO2) dioxide from the plasma polymer filin. The plasma polymer acts as a nano-reactor for the growth of TiO2 nanoparticles
