Abstract
Background:
This research indicated that such abstract are more informative and more
readable, in field of preparation of nanocomposite materials.
Aim:
The purpose of this work represented by decoration of Carbon Nanotubes (CNTs) with nanoparticles
using co-precipitation method and exhibit different physical properties from those of CNTs
alone and its appropriate for this particular journal.
Methods:
Preparation MWCNTs surface by Ag/ZnO nanoparticles using two steps represented by
acid treatment of MWCNTs in a mixture acid of sulfuric acid (95% H2SO4) and nitric acid (65%
HNO3) at 3:1 ratio and second step represented by decoration of Ag/ZnO nanoparticles on FMWCNTs
using co-precipitation method to prepare ZnO/Ag nanoparticles decorated on F-MWCNTs
as nanocomposite material.
Results:
The results of this work reveal the decoration of Ag-doped ZnO nanoparticles on the FMWCNTs
was achieved without any impurities as shown in XRD, Raman spectra and FTIR and
FESEM observations reveal that Ag-doped ZnO nanoparticles have spherical morphologies and adhered
on the functionalized MWCNTs, with diameters are about 22-30 nm. Also it is clear that there
were no any other materials on the surface of F-MWCNTs except ZnO and Ag which verifies the
results obtained from XRD and EDS analysis.
Conclusion:
In this article, Ag-doped ZnO nanoparticles have been successfully decorated on to modified
MWCNTs by an in-situ co-precipitation method. From XRD results, it can be seen that the (002)
peak of MWCNTs slightly increased after the addition of Ag-doped ZnO nanoparticles. Raman spectra
and FTIR analysis confirmed the formation of Zn-C or Zn-O-C bonds between acid-treated MWCNTs
and Ag-doped zinc oxide. The FESEM and EDS analysis revealed that the decoration of Ag-doped ZnO
nanoparticles on the F-MWCNTs was achieved without any impurities. Finally, the small sizes Agdoped
ZnO NPs deposited on F-MWCNTs make it very promising for biomedicine applications.
