Resumo
Due to the remarkable properties of graphene oxide (GO) and its possibility
of functionalization,GOhas been used in many applications such as nanocomposites.
GO nanosheets have been shown to improve the properties of the polypropylene
(PP) matrix, for instance, its strength, gas barrier, thermal, and electrical conductivity.
As PP has relatively low cost and varied applications, this work aims to study the
changes in its thermal, morphological, and mechanical properties, due to the incorporation
of GO in the PP matrix. GO was synthesized from graphite by a modified
Hummers method. The nanocomposites PP/GO with 0.1, 0.2, and 0.3 wt% of GO in
the PP matrix were obtained using a twin-screw extruder and an injection molding
machine via a melt blending process. The nanocomposites PP/GO were characterized
by FE-SEM and Izod impact test. In addition, the GO nanosheets were also
characterized by Raman spectroscopy, ATR-FTIR, FE-SEM, and XRD, therewith
correlation between properties was discussed.
