Effect of carbon nanotubes produced by using different methods on electrical and optical properties of zinc oxide-carbon nanotube composite

Abstract

In this study, carbon nanotubes, which were produced by using chemical vapour deposition and mechano-thermal methods, were combined with zinc oxide matrix at different ratios and the effects of the nanotubes on electrical and optical properties of zinc oxide were examined. It was observed that electrical conductivity of zinc oxide at room temperature increased with the increase in the reinforcement rate both in carbon nanotube reinforced samples produced by using chemical vapour deposition and those produced by using the mechano-thermal method. Carbon nanotube reinforced samples produced by using chemical vapour deposition yielded relatively better results for the same reinforcement rate.
