The surface composition of aminated polypropylene films (PP-g-NH₂) and their adhesion to polycarbonate (PC) film were evaluated. The detection of amine groups on PP-g-NH₂ surfaces was obtained by X-ray photoelectron spectroscopy (XPS). Contact angle measurements showed a decreased in the polarity on PP-g-NH₂ surface The adhesion between laminated films of PP-g-NH₂ and PC was evaluated by T-peel test and optical microscopy. PC deposited on the PP-g-NH₂ surfaces was confirmed by FTIR-ATR and SEM analysis of delaminated films, which is an indicative of an interaction between reactive sites of each polymer. The adhesion performance between PC and PP was improved by using amine modified polypropylene (PP-g-NH₂).
