Fabrication of (Al 2 O 3 /CdO) metal and ceramic matrix composites reinforced CMC via laser ablation and studying their optical, thermal, and electrical properties for optoelectronic applications

Abstract

Abstract Aluminum oxide and cadmium oxide nanoparticles have been reinforced carboxymethyl cellulose (CMC nanoparticles using a laser ablation process. The effect of change the content of cadmium oxide on the optical, thermal and electrical conductivity properties have been evaluated. The synthesized films have been investigated via various techniques. The strong ion interactions and arrangement of big ion clusters that produced a significant quantity of ion clusters may have caused the Al2O3/CdO peaks to rise again. FTIR spectra of the polymer nanocomposites obtained the interactions between the Al2O3/CdO -NPs and pure CMC. The energy gap values decrease from 5.35 eV to 2.98 eV in direct transition by increasing the content of cadmium oxide nanoparticles. The values of TGA indicate that the thermal stability of the produced materials has been increased by the addition of Al2O3/CdO nanoparticles. Dielectric results found that as Al2O3/CdO NP concentrations increase, the dielectric constant and dielectric loss increase as well. Arc length in CMC/Al2O3 reduces as cadmium oxide content rises, indicating enhanced conductivity. The synthesized nanocomposite fil could be suggested for optoelectronic applications.
