Resumo
Graphene oxide, graphene and derivatives thereof has shown a significant
increase in the number of scientific research devoted to their study. One of the
most studied areas is its application as nanofillers in polymer nanocomposites.
This paper describes obtaining graphene oxide by simplified Huang procedure, by
chemical oxidation. Purified aqueous dispersions of graphene oxide were
sonicated for 15 min, 1.0 h; 2.0 h; and 3.0 h. Thickening of sonicated dispersions
was accompanied by rheological measurements. After drying and grounded, the
obtained materials were characterized by techniques such as XRD, FTIR, SEM
and TEM. The reduction in average diameter with sonication time was followed by
laser particle size distribution assays. Examples of substantial gains in mechanical
and barrier properties obtained with graphene oxide/EVOH nanocomposites are
shown.
