Abstract
AbstractPolymer nanocomposites of poly (vinyl alcohol) (PVA), poly (vinyl pyrrolidone) (PVP) filled with various concentration of nanocomposite (Zn0.97Al0.03O: 1 wt% GO)x; x = 1, 3, 5, and 7 wt% were prepared by solution mixing and then cast into films. X‐ray combined with energy dispersive spectroscopy (EDS) data elucidated the successful preparation of pure PVA/PVP and filled films. The identifiable diffraction lines are ascribable to the presence of filler (Zn0.97Al0.03O: 1 wt% GO) that further established by the data of EDS as well as selected area electron diffraction pattern (SAED) achieved by high‐resolution transmission electron microscopy (HRTEM) measurement. The optical band gap (Eg) of composite shows a significant decrement from 5.2 to 4.7 eV as the nanocomposite fillers were varied from 0 to 7 wt%. In addition, the refractive index (n), optical dielectric loss (ε2), and optical conductivity (σopt) were investigated. The PVA/PVP filled with merely 1 wt% of the particle has an extremely high dielectric permittivity and conductivity.
