ABSTRACT: This research was based on the manufacture of new composite
materials that offer technological possibilities in the development of new
devices with greater efficiency. Electrospinning was used to form nylon
66/-tetra-(para-aminophenyl) porphyrin (H2T(p-NH2)PP)/graphene oxide
(GO) composite film. Graphene oxide coatings were obtained from graphite,
through mechanical exfoliation followed by calcination and ultrasonic agitation
in an oxidant solution. These samples were characterized under SEM, FTIR, Raman
spectroscopy, UV-vis and R-X techniques. On the other hand, H2T(p-NH2)PP
was synthesized in two stepsprocess by the Rothemun reaction and the Adler Method and it was
integrated within nylon polyamide fibers by direct addition of a
hexamethylenediamine/adipoyl chloride reactant mixture. The polymerization of
the nylon/H2T(p-NH2)PP species occurs in such a way that
it starts or ends on the four peripherals-NH2 groups, connected
and located in the same molecular plane of H2T(p-NH2)PP,
forming nylon chains at the periphery of the macrocycle. The association of GO
with nylon/H2T(p-NH2)PP fibers is performed by
dipole-dipole interaction and hydrogen bonding. To take advantage of the
properties of these materials, they were combined as a ternary composite.
