abstract = "The development of polyaniline and graphene oxide composites aims
to join the unique properties of each material for aerospace
applications. The present paper demonstrates an easy and quick
method, compared to the ones found in the literature, to obtain a
composite made with polyaniline doped with dodecylbenzenesulfonic
acid, a combination commonly called polyaniline, and graphene
oxide. Nowadays, the most common studied methods are
electrochemistry and in situ chemical polymerization. Differently
from these methods, the films were obtained by a physical mixture
of equimolar suspension of graphene oxide (4 mg/mL) with 3
concentrations of polyaniline powder: 25; 50 and 75%, being
compared to pure graphene oxide and polyaniline. The morphology
and structure behavior of all the films were studied, besides the
bonding nature between both materials. The films were analyzed by
scanning electron microscopy, X-ray diffraction, Fourier transform
infrared spectroscopy, and differential scanning calorimetry. The
apparent interaction between graphene oxide corrugated sheets and
polyaniline grains was verified by scanning electron microscopy
images. It can be noticed, as the concentration of polyaniline
increases, that more polymer was entrapped. To prove the formation
of polyaniline/graphene oxide composite, X-ray diffraction and
Fourier transform infrared spectroscopy techniques demonstrated
the changes on graphene oxide crystallographic plans and on the
chemical bonding between polyaniline and graphene oxide,
suggesting an interaction between polyaniline and graphene oxide,
especially in the composite with 50% polyaniline/50% graphene
oxide. Differential scanning calorimetry was used to highlight
this effect through the increase in thermal stability. The method
of physical mixture was efficient to obtain the polyaniline/
graphene oxide composites.",
