摘要

The present study aims to boost the structure and optical characteristics of polymethylmethacrylate (PMMA) incorporated with silicon carbide (SiC)-nickel oxide (NiO) promising nanoceramic to apply in many flexible optoelectronics and photonics fields. The films of (PMMA/SiC-NiO) were prepared using the casting technique. The structure and optical characteristics of PMMA/SiC-NiO nanostructures were investigated. The optical characteristics were studied at wavelength (λ = 320–920 nm). The results of optical characteristics for PMMA/SiC-NiO nanostructures indicate that absorption coefficient (α), absorbance (A), extinction coefficient (k), refractive index (n), imaginary (ε2) and real (ε1) parts of dielectric constant, and optical conductivity (σ) of PMMA increased, while energy band gap (Eg) and transmittance (T) reduced with a rise in SiC-NiO NPs content. The PMMA absorbance enhanced of 89.2% at UV region (λ = 360 nm) with rising SiC-NiO NPs content to 2.8%, hence these nanomaterials can be useful in many photonics and optical fields. The PMMA energy gap reduced from 3.42 to 2.8 eV with increasing SiC-NiO NPs content to 2.8%. The thickness of the PMMA-SiC-NiO nanostructure films was found to be in the range is 30 μm The particle size distribution, shows that the SiC-NiO nanoparticles are uniformly dispersed within the PMMA matrix with an average size of 40–80 nm. The final findings demonstrated that PMMA/SiC-NiO nanostructures can be considered as a potential nanomaterials to employ in a variety of promising optical and nanoelectronics applications.
