The work shows the preparation and characterization of composite materials
using a polymer as matrix (ABS) and carbon black or a graphenic material
(graphene and graphene foam). The materials were individually mixed with the
polymer and the process parameters were established in an extruder with
temperature control starting at laboratory conditions and up to 600 °C. The
process parameters were adjusted to form filaments that were subsequently
used in a 3D printer. The parameters of the printing process were adjusted to
achieve the production of flat prototypes. These prototypes were characterized
by Digital Optical Microscopy, Contact Angle, Surface Energy, Electrical
Conductivity, XPS, and SEM. The degree of homogeneity of the prototypes and
the working ranges for the graphene material concentrations were determined.
Even though the characterizations were done in flat samples, 3D printing allows
obtaining a great diversity of structure that broaden the diversity of applications
for such kind of composite materials.
