abstract = "Bionanocomposites with properties similar to those of conventional
polymers derived from petroleum have shown scientific and
industrial interest. The current research discuss the effect of
graphite nanosheets (GNS) addition on electrical, electromagnetic,
and mechanical properties and also on morphological aspects of the
natural polymer poly(hydroxybutyrate-co-hydroxyvalerate)
(PHBV)/GNS nanocomposites and neat PHBV prepared by casting
method. Nanocomposite of PHBV/1.00 wt% GNS showed good electrical
conductivity values, extending the scope of application of these
materials, such as in reflectors. One of the objectives of this
study was to investigate the effect of different contents of GNS
in neat PHBV using dynamic mechanical analysis (DMA), which showed
that the addition of GNS in PHBV matrix improved the DMA
properties. Transmission electron microscopy (TEM) shows good
dispersion of GNS in the PHBV matrix with stacked and intercalated
graphite layers and XPS confirmed the presence of carbon and
oxygen in the graphite nanosheets surface.",
