Electrical and optical properties of cadmium oxide carbon nanotube nanocomposite

SUMMARY In this study, composite materials reinforced with carbon nanotubes (CNT) containing cadmium oxide were produced and investigated optical and electrical properties of them. Carbon nanotubes which used support materials were synthesized by chemical vapor deposition. After then, they were reinforced in to the cadmium oxides which were sold by commercial. As an other group, cadmium oxides were synthesized by sol-gel method and reinforced carbon nanotubes with different rate. Synthesized CNT's were subjected to TEM investigation. Obtained CNT 's were also subjected to SEM as structural. After those, gained composite samples were investigated for both electrical conductivity, changing temperatures and optical properties by UV-vis spectrometers. It was clear, as a result that electrical conductivity were increased by raising CNT rates for both groups. Beside composites containing CdO, synthesized by sol-gel method have higher conductivity than composites containing CdO bought by commercial have. To sum up, CdO composites synthesized by sol-gel have both higher conductivity and optical properties comparing with commercials have.
