This work aims at optimizing an atmospheric pressure dielectric barrier discharge (DBD) plasma copolymerization involving maleic anhydride and vinyltrimethoxysilane used to generate coatings carrying carboxylic groups. A constant functionalization everywhere in the reactor is targeted, with coatings thoroughly characterized by X‐ray photoelectron spectroscopy, scanning electron microscopy, Auger and atomic force microscopy. Results show that a constant carboxyl functionalization involving between 20% and 25% of the carbon atoms was reached for particular experimental conditions. The importance of the carrier gas nature (He or Ar) on the coatings is also highlighted.
