abstract = "Graphene-related materials (GRM) are promising materials to
improve mechanical, electrical, and optical polymer properties.
Adding multi-wall carbon nanotubes (MWCNT) on GRM nanocomposites
promotes synergistic effects on its electrical properties and
electromagnetic interference shielding effectiveness (EMI SE).
This study focused on evaluating the addition of MWCNT on three
different polycarbonate (PC)/acrylonitrile butadiene styrene
(ABS)/GRM nanocomposites. These hybrid nanocomposites were
prepared by melt mixing using extrusion and injection-mold
processes. The morphologies of the nanocomposites were evaluated
by field emission gun scanning electron microscopy (FEG-SEM), and
their proprieties were characterized by X-ray diffraction (XRD),
oscillatory rheological, dielectric spectroscopy, and EMI SE
analyses. The electrical behavior of all hybrid nanocomposites was
anisotropic due to the injection-molded preparation process. The
lateral size, thickness, and production method of the GRM were
indicated to be critical factors for the electrical and EMI SE
behaviors of these composites. The nanocomposites with GRM2, which
had the smallest lateral size and thickness (graphene
nanoplatelets), promoted total attenuation levels around 20 dB
with 1.5 wt% of MWCNT, matching the EMI SE required for some
commercial applications.",
