The synthesis of hybrid composite materials based graphene, maintain the
attention of researchers, in the search for methods to scale production levels
and reduce environmentally undesirable effects. In this paper, we synthesize
graphene functionalized with AgNPs in aqueous solution. Graphene was
obtained the exfoliation of graphite using the extract of the plant and sonication.
In a process of chemical reduction in the presence of extract of bursera
microphylla (torote) were stabilized silver nanoparticles. Flakes highly
transparent composite material were observed in optical microscope. The
optical properties were studied by means of photospectroscopy of UV-Vis and
FTIR infrared spectroscopy, both methodologies are consistent in pointing out
the existence of bands of absorption and vibrational bands associated with the
presence of nanostructures of silver metallic and carbon, respectively. The
structural and morphological study by TEM, confirmed the existence of laminar
structures with built-in silver nanostructures in micrometric extension. The FFT
Digital Micrograph obtained allowed to determine the interplanar distances that
confirm their presence. This was also ratified in analysis of x-rays (EDS) energy
dispersive spectrometry. This green synthesis method offers a choice for the
production of a nano-material of graphene funtionalized with silver
nanoparticles with low energy consumption, without use chemicals hazardous
and low economic and environmental cost.
