Abstract
        By applying ammonia plasma treatment and chemical ethylenediamine treatment, amine functionalities were observed in 
the poly(ethylene terephthalate) (PET) films surfaces. The modified surfaces were characterized by FTIR, fluorescence, 
wide-angle X-ray diffraction (WAXD) and atomic force microscopy (AFM). Ethylenediamine treatment yielded fewer surface 
amino groups, and in addition a change in crystallinity as well as degradation of PET. Treatment time dependency of amine 
concentration is depicted, more amines were incorporated after exposure to a higher energetic plasma resulted by the 
higher ionisation in the plasma. At higher energies at longer treatment, an increase of the amine concentration was 
observed. For surface activation, plasma treatment was more efficient than chemical treatment.
