|Abstract(s):||This work intends to study the chemical and physical modifications of natural cork agglomerate after plasma treatment using dielectric barrier discharge (DBD). Different experimental techniques were used to evaluate the surface alterations of the substrate pre- treated with DBD plasma, namely, static and dynamic contact angle, surface energy, Fourier transform infrared spectroscopy (FTIR), energy dispersive spectroscopy (EDS), scanning electronic microscopy (SEM) and differential scanning calorimetry (DSC). Plasma discharge greatly increases the wettability and surface energy of the samples. Chemical and physical analyses of the cork agglomerate confirmed considerable surface modification.|
