Abstract:
Polymer nanocomposites of poly (vinyl alcohol) (PVA), poly (vinyl pyrrolidone) (PVP) filled with various concentration of nanocomposite (Zn 0.97 Al 0.03 O: 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 (Zn 0.97 Al 0.03 O: 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 ( E g ) 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 ( ε 2 ), and optical conductivity ( σ opt ) were investigated. The PVA/PVP filled with merely 1 wt% of the particle has an extremely high dielectric permittivity and conductivity.
