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). (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 336-342, 2011
