Abstract:
In this research the carbon Nanotubes were doped by TiO2, MgO, CuO and ZnO, such that four samples from each metal oxide were prepared at different annealing temperatures (450,500,550 and 600)C0. The optical properties like absorption coefficient and refractive index were studied using ultra violet spectrometer. The electrical properties like conductivity and dielectric constant were also investigated by using software program. The temperature increase decrease the absorption coefficient TiO2 and CuO and for ZnO and MgO while it increase with temperature decrease the conductivity and the dielectric constant for TiO2, CuO and ZnO, while it increase them for MgO to briefed. These results were explained theoretically
