Abstract

In this work, graphene oxide (GO) was first obtained by chemical exfoliation. Then it was melted by hot compression with polypropylene grafted with maleic anhydride (PP-g-MA). The PP-g-MA/GO (1% and 3% GO wt.%) were applied to prepare polypropylene/PP-g-MA/GO nanocomposites by extrusion. Pelletized samples obtained by extrusion were stamped from plates obtained by compression in a bench press and these materials were characterized through FTIR and tensile tests. The GO was also characterized by Raman spectroscopy, X-ray diffraction and FTIR. The results indicated that GO acted as a plasticizer, reducing the mechanical property values in comparison with pure polypropylene.
