Abstract

The poly(ethylene terephthalate) thin films were exposed to vapour of ethylenediamine for treatment times of 10, 15, 17, 20 and 30 min in order to modify the structure of their surface. The presence of amine and amide groups make possible the further derivatization of modified poly(ethylene terephthalate) films due to ability of these units to react with isocyanates, expoxides, esters, phosphorus trichloride. The experimental Fourier Transform Infrared Attenuated Total Reflexion (FTIRATR) spectra provided information related to the changes in the chemical structure of poly(ethylene terephthalate) after each step of treatment. The FTIR ATR analysis was performed in a wide range of wavenumber 400–3000 cm-1 paying particular attention to typical CH2, C=O, amide I, amide II and ester vibrations..
