Ameliorating the Features of TiN/SiO2 Promising Nanoceramic Doped Optical Polymer for Multifunctional Optoelectronics Applications

Abstract

The goal of this work is to improve the optical and structural properties of titanium nitride(TiN)- silica(SiO₂) promising nanoceramic doped polystyrene (PS) to apply in flexible nanoelectronics and optical fields. The films of (PS-TiN-SiO₂) were produced utilizing the casting process. The structure, and optical properties of (PS-TiN-SiO₂) nanostructures were examined. The structure characteristics of (PS-TiN-SiO₂) nanostructures were tested using FTIR and optical microscope(OM). The OM images confirmed the good dispersion of (TiN-SiO₂)NPs throughout the (PS) matrix, whilst the FTIR revealed a physical relationship between the polymer (PS) and the nanoparticles. The optical characteristics were examined at wavelengths (λ = 320-920nm). The study found that when TiN-SiO₂ NPs reaching 2.8 wt%, the absorbance increased of 32.8% and transmission decreased of 11.3% at wavelength(360 nm), making them perfect for various optical fields. When TiN-SiO₂ NPs concentration reached of 2.8 wt%, the energy gap of PS decreased to 2.53eV and refractive index increased from 2 to 2.24 making (PS-TiN-SiO₂) nanostructures ideal for optoelectronics nanodevices. As the concentration of TiN-SiO₂ NPs rises, the other optical parameters(absorption coefficient, extinction coefficient, real and imaginary dielectric constants, and optical conductivity) were increased. Finally, the results confirmed that the (PS-TiN-SiO₂) nanostructures may be considered as a future nanosystems to exploit in a variety of potential nanoelectronics and optics applications.
