ABSTRACT |
|
|
|
Zinc oxide (ZnO) nanostructures were
synthesized by microwave assisted hydrothermal route. Polyaniline (PANI)
based nanocomposite filled with ZnO nanoparticles were prepared by
in situ chemical oxidative polymerization method of aniline in an
acid medium with ammonium peroxydisulfate as an oxidant. The
composition, morphology, and structure of the polymerand the
composite were characterized by Fourier-transform infrared
spectroscopy (FTIR), X-ray diffraction, scanning electron
microscopy, and ultraviolet-visible spectroscopy. The flaky shaped
structure of PANI/ZnO nanocomposite confirms the smooth PANI layer
on the surface of ZnO nanoparticles and formation of a core-shell
structure. Furthermore, the PANI/ZnO nanocomposite possess high
antimicrobial activity against the model microbes Escherichia coli
(Gram-negative) and Staphylococcus (Grampositive). It is expected
that the PANI/ZnO nanocomposite is the promising material for the
application in the biomedical field. |
