Synthesis of nanostructured Bi₂O₃NPs using laser ablation technique and its effect on the optical, thermal, and conductivity characterization of the PEO/CMC blend

Nano-sized materials such as bismuth oxide nanoparticles (Bi₂O₃NPs) have been extensively used in optical, chemical, electronic, and engineering area In this work poly ethylene oxide /Carboxymethyl Cellulose (PEO/CMC: 50/50%) nanocomposite films were prepare via dispersing Bi₂O₃ NPs inside via One-Pot Pulsed Laser Ablation route (OPPLA). The physical characterization of the fabricated samples were analysis. XRD confirm the semicrystalline shape of nanocomposites samples. The estimated Bi₂O₃NPs size as evaluated via XRD was 16 ± 6 nm. The FTIR spectra showed the decreased of the peak intensity with increasing bismuth oxide nanoparticles denotes the intermolecular interactions between Bi₂O₃NPs and PEO/CMC composite. Optical energy gap (E_g) of PEO/CMC–Bi₂O₃NPs nanocomposites showed decrease as Bi₂O₃NPs wt. % increases. TGA analysis of filled sample showed refinement in their thermal stability in air compared to the pure samples.
