Plasma polymerization of hybrid organic–inorganic monomers in an atmospheric pressure dielectric barrier discharge

Both a hybrid organic–inorganic monomer and a purely organic monomer were atomized and introduced in an atmospheric pressure dielectric barrier discharge (DBD), with the aim of evaluating the barrier properties of the coatings obtained. After thorough analysis, the barrier properties of the plasma polymers were related to their physical and chemical properties. The physical properties of the coatings were determined by SEM-analysis as well as by profilometry. The chemical structure was revealed by 13C- and 29Si-CP/MAS solid-state NMR measurements and ATR-FTIR analysis. shown that atmospheric pressure plasma polymerization of hybrid polymer precursors leads to coatings with excellent barrier properties due to the unique synergistic effect of the organic and the inorganic network structures that are formed in the plasma.
