Structural and linear/nonlinear optical characteristics of flexible polypyrrole/CuO polymeric composite films
Abstract
The composite (PPy/CuO) films are created using the solution casting solution method by mixing the polymer polypyrrole (PPy) with copper oxide nanoparticles (CuONPs) at different concentrations of CuO (4%, 6% and 8%). The XRD confirms the effective fabrication of the composite (PPy/CuO). The impact of CuO on the optical and structural characteristics was studied. The addition of CuO enhances the refractive indices ( of PPy from 1.42 for pure PPy to 1.55 for PPy with 4% CuO, and further to 1.69 for PPy with 8% CuO. The dispersion energy of pure polypyrrole (PPy) is 4.55eV, which increased to 5.31eV when doped with 4% CuO. Furthermore, the increasing of CuO concentration to 6% and 8% resulted in higher dispersion energies, respectively, of 5.87 and 6.14eV. The oscillation energy decreased from 4.43eV for PPy to 3.76, 3.41 and 3.25eV for PPy/4%CuO, PPy/6%CuO and PPy/8%CuO, correspondingly. The introduction of …
