Study the optical properties of polyaniline-multiwelled carbon nanotubes nano composite

Abstract EN

The study includes the recording of the spectrum of absorbance and transmittance for the blend solutions for polyanilin with carbon nanotube) and calculating the absorption coefficient and other optical constants.

The samples have been prepared in different weight concentrations (0%,1%,3%,5%) (PANI- carbon nano tube ).

The values of absorbance, the refractive index values of pure polymer and its additives are increasing with the increase of the concentrations of these polymer, Noting that the increment of absorption coefficient values under the influence of addition caused by increasing density of the solutions as a result of the increased concentrations, that led to the increase of light absorbed because the interaction of the electromagnetic wave and the large molecules of the polymer increases with concentration, The results show that decreasing in the values of transmittance with all concentrations, the values of reflectance are increases with increasing concentration before and after the doping, the results showed decrease energy gap with increasing ratio of dopig.-
