A two step process was used for the cellulose/chitin mix fibers modification: the first one consists in cold plasma activation followed by the second step the reaction with different chemical modifiers by subsequent impregnation or impregnation/coupling reaction. The activation has been performed under the action of four kinds of cold plasma discharges (discharge gases: air, oxygen, nitrogen and argon). The N-isopropylacrylamide, acrylic acid and oleic acid are used as modifiers. The modified samples were characterized by ATR-FTIR spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, thermogravimetry and differential thermal analysis. All results confirm the morphological and structural changes after plasma treatments which determine the modification of the cellulose/chitin mix fibers.
