Ameliorating and Tuning the Structural, Morphological, and Optical Characteristics of Chromium Oxide/Silicon Carbide Promising Hybrid Nanocomposites Doped PMMA for Futuristic Nanoelectronics and Photonics Applications

In the current study, films of promising nanocomposites were fabricated from poly-methyl methacrylate(PMMA) filled with chromium oxide (Cr₂O₃) and silicon carbide(SiC) nanostrucures to employ in several advanced nanoelectronics and optical fields. The PMMA/Cr₂O₃/SiC nanocomposites have remarkable characteristics compared with other types of nanocomposites included inexpensive, excellent optical properties, good physical and chemical behaviours. The structural and optical properties of PMMA/Cr₂O₃/SiC nanocomposites films were tested. Results confirmed that the PMMA absorbance increased of 26.3% and 27.6% at λ = 380 nm (UV/spectra) and λ = 580 nm (VIS/spectra) when the Cr₂O₃/SiC NPs ratio reached of 5.7 wt.%. The PMMA transmittance decreased of 14.8% and 13.4% at λ = 380 nm and λ = 580 nm, these results make the PMMA/Cr₂O₃/SiC nanocomposites films are promising nanostructures for nanoelectronics and optics applications. The indirect allowed energy gap reduced from 3.82 eV to 3.47 eV with rising concentration of SiC/Cr₂O₃ NPs to 5.7 wt.%. The optical factors of PMMA improved with rising SiC/Cr₂O₃ NPs concentration. Finally, the attained results showed the PMMA/Cr₂O₃/SiC nanocomposites are promising nanocomposites and major key for potential nanoelectronics and optics applications.
