摘要

The present work aims to prepare nanostructures of silicon carbide (SiC) and ferrite (CoFe2O4) doped with poly methyl methacrylate (PMMA) and coated with a metal layer of aluminum (Al) nanomaterial to employ in several various electronic and optical applications. The structural and optical properties of PMMA-CoFe2O4-SiC/Al nanocomposites were studied. The obtained results indicate that the optical absorption of PMMA at wavelength (λ) = 360 nm increased of 56.5% while the transmittance decreased of 45.6% with rising the content of nanoparticles to (3 wt%). This behavior making them appropriate for a variety of optoelectronics applications. When the CoFe2O4-SiC NPs content reached to (3 wt%), the energy gap of PMMA dropped from 3.4 to 2.2 eV. At a wavelength of (λ) = 360 nm, the refractive index of PMMA increased from 2.40 to 2.64. The extinction coefficient increased from 0.007 to 0.016. Both the real and imaginary dielectric constants increased from 5.78 to 6.98 and from 0.04 to 0.08 with rising the content of nanoparticles to (3 wt%). These results can be considered as key for various optical and optoelectronic nanodevices.
