High energy Gamma Irradiation processing of PVDF/BaxSr1-xTiO3 Bio-nanocomposite on Optical Properties

Abstract

Polymer-ceramic bio-nanocomposites, consisting of Barium Strontium Titanate BaxSr1-xTiO3 (x= 0.6, 0.7) (BST) as fillers and Poly (vinylidenefluoride) (PVDF) as matrix, have been fabricated by using a spin coating method with (BST) filler contents of (25,40) vol%. (BST) nanopowder was synthesized by hydrothermal method. The optical properties of (PVDF/BST) nanocomposites were studied from the absorbance spectrum, the absorbance of the BaxSr1-xTiO3 (x= 0.6, 0.7) nanocomposites increase after gamma irradiation with doses (4.32 kGy) and (4.98 kGy). The optical energy gap for the allowed direct electronic transition of (PVDF/BST) nanocomposite with different filler contents of (BST) decrease after gamma irradiation with doses (4.32 kGy) and (4.98 kGy).
