Preparation, characterization and electrical conductivity studies of MWCNT/ZnO nanoparticles hybrid
چکیده انگلیسی

Multiwall carbon nanotubes (MWCNTs) were decorated with crystalline zinc oxide nanoparticles (ZnO NPs) by wet chemical route to form MWCNT/ZnO NPs hybrid. The hybrid sample was characterized by scanning and transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Electrical conductivity of the hybrid can be tuned by varying the ZnO NPs content in the hybrid. In order to investigate the effect of nanoparticles loading on the conduction of MWCNTs network, electrical conductivity studies have been carried out in the wide temperature range 1.5–300 K. The electrical conductivity of the hybrid below 100 K is explained with the combination of variable range hopping conduction and thermal fluctuation induced tunnelling model.
