Synthesized Polymeric Nanocomposites with Enhanced Optical and Electrical Characteristics Based on SiO2 Nanoparticles for Multifunctional Technological Applications
Composites of polyvinyl alcohol and polyvinyl pyrrolidone (PVA/PVP) reinforced with different silicon dioxide (SiO2) loadings (0, 2, 4, and 6) wt.% were obtained via the solution casting method. The electrical and optical properties have been investigated. Fourier-transform infrared ray (FTIR) analysis revealed that the incorporation of SiO2 NPs resulted in an interaction with the polymer matrix. Physical interactions between the (PVA/PVP) polymer matrix and SiO2 NPs have been shown by FTIR analysis. The increase in SiO2 nanoparticle ratio in the PVA/PVP/SiO2 nanocomposite results in a corresponding increase in absorbance and decrease in transmittance. The PVA/PVP/SiO2 nanocomposite exhibited a reduction in energy gap, decreasing from 4.2 eV observed in pure PVA/PVP to 2.6 eV for allowed indirect transition and 4 eV to 2.6 eV for forbidden indirect transition, upon the incorporation of SiO2 nanoparticles at a concentration of 6 wt.%. This result is deemed a key for various optical fields and optoelectronics nanodevices. The weight percentages of SiO2 nanoparticles exhibit a positive correlation with their absorbing coefficient, extinction coefficient, index of refractive, real and imaginary components of dielectric constants, and optical conductivity. The investigation of the nanocomposites has revealed that an increase in the concentration of SiO2 nanoparticles leads to an elevation in both the dielectric constant and dielectric loss, while an increase in the frequency of the applied electric field results in a decrease in these properties. The increase in frequency and weight content of SiO2 NPs results in a corresponding increase in AC electrical conductivity. The results confirm that PVA/PVP/SiO2 films nanocomposites have excellent optical and electrical properties, which could encourage the nanocomposites' application in different electric and optoelectric uses.
期刊介绍：
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
