Synthesis and Study Implications of Including Cobalt Oxide Nanoparticles on Structural and Optical Properties of Polyvinyl Alcohol Polyacrylic Acid Blend Films

Abstract

Poly Vinyl Alcohol / Poly Acrylic Acid (PVA/PAA) pure polymeric films made using the solution casting technique , It is strengthened by cobalt oxide nanoparticles (CoONPs) through deposition approach at calcination temperatures (800 Cº), In different weight percentages ((pure,1,3,5,7and 9) % wt.), burned at different temperatures (800 Cº) . XRD analysis of the as-synthesized nanomaterial powder indicated that cobalt oxide nanoparticles were obtained at the calcination temperature (800 C°). Heat treatment promotes continued crystallization, leading to an expansion in the dimensions of nanoparticles. The electron microscopy FESEM outcomes showed that the PVA/PAA polymeric film seems uniform and monolithic, and once used (PVA/ PAA:CoO 7 % ( , It forms widely distributed agglomerates within nanocomposite membranes. Show The FTIR picture CoONPs don't negatively impact the structure of polymers. No covalent connections exist between PVA , PAA and CoONPs. The visual characteristics of the films reinforced with CoO nanoparticles demonstrate their influence on optical transmittance over the (200-1100) nm wavelength range, alongside a decline in energy band gap values from 5.07 eV to 4.68 eV .
