Fabrication of PMMA/PEG/SnO2/SiC quaternary multifunctional nanostructures and exploring the microstructure and optical features for radiation attenuation and flexible photonics applications
The current study aims to synthesize of poly-methyl methacrylate (PMMA)-polyethylene glycol (PEG) doped with tin oxide (SnO2) and silicon carbide (SiC) nanostructures for gamma ray attenuation and photonics applications. The microstructure and optical characteristics of PMMA-PEG-SnO2-SiC nanostructures were studied. The obtained results indicated that the PMMA-PEG absorbance increased of 69.6% and the transmittance decreased of 46% when the SnO2/SiC NPs ratio rise to 4.8 wt%. The PMMA-PEG’s energy gap (Eg) decreased to 3.95 eV when the SnO2/SiC NPs ratio reached of 4.8 wt%. The optical constants (coefficient of absorption (α), index of refractive (n), coefficient of extinction (k), real (ε1) and imaginary (ε2) parts of dielectric constants, and conductivity of optical (σop) were increased of 69.6%, 22.1%, 69.6%, 39.4%, 76.3, and 76.3%, respectively, when SnO2/SiC NPs reached of 4.8 wt% at wavelength (λ = 540 nm). These results make the PMMA-PEG-SnO2-SiC nanostructures are appropriate for optical and electronic applications. Finally, the gamma radiation attenuation coefficients were increased with rising nanoparticles concentrations. The (PMMA-PEG-SnO2-SiC) nanostructures have highest attenuation coefficients for gamma radiation.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
