Abstract This work aims to analyze the effects of cold atmospheric air plasma treatment of antimicrobial chitosan film with different levels of thymol. Optical characterization of the dielectric barrier discharge showed the generation of reactive nitrogen and oxygen species by the system. A significant increase (p < 0.05) in the surface roughness was observed after cold plasma treatment of the films. No significant difference (p > 0.05) was observed in the thermal profile of the plasma-treated films. A significant increase (p < 0.05) in the thymol diffusion coefficient was observed after the plasma treatment for all the active films. More >
