Modification and development of the optical, structural, thermal and electrical characterization of Chitosan incorporated with Au/Bi2O3/Mo NPs fabricated by laser ablation

The molecular structures of pure polymer (chitosan) incorporated with ternary metal nanoparticles (Au/Bi2O3/Mo) synthesized by laser ablation have been performed ia FT-IR and XRD. The surface of the synthesized samples has been investigated ia SEM. Thermal, electrical, and dielectric haracterization have been performed to utilized in energy applications. XRD patterns display the amorphous nature of chitosan (Cs), characterized by two hump peaks at 2 =11.34(o) and 2 =19.57(o), which disappeared by doped with Au/Bi2O3/Mo NPs. FT-IR spectra revealed that thereare complexation between Cs and Au/Bi2O3/Mo NPs took place in amorphous regions. SEM displays grains with rectangular shape after adding different filling nanoparticles, and rod-shaped formed on the surface of the samples.TGA curves obtained the enhancement in the thermal stability of samples . The AC conductivity of the samples increased by the addition of Au/Bi2O3/Mo NPs. The results confirm that nanocomposite of Cs/metal have excellent thermal and electronic haracterization, which may suggest the utilization of these nanocomposites in energy storage.

Automated summary

The molecular structures, surface morphology, and thermal/electrical properties of chitosan incorporated with ternary metal nanoparticles (Au/Bi2O3/Mo) were investigated. The results showed that doping with metal nanoparticles improved the thermal stability and AC conductivity of the samples. This study suggests the potential utilization of Cs/metal nanocomposites in energy storage.
