Prediction Study of Thermoelectric Properties of TiO2 Nanoparticles and Effect on PVA/SiO 2 Hybrid Films Synthesized by sol-gel Method

Abstract

Abstract We use an ab initio approach to look into the structural, electronic band structure, and thermoelectric properties of titanium dioxide (TiO2 in rutile phase), and we then use TiO2 to create its effects on sol-gel-produced polyvinyl alcohol/silicon dioxide (PVA/SiO2) hybrid films. The synthesis of the hybrid films involved the incorporation of 1% TiO2 nanoparticles in the PVA/SiO2 matrix. The thermoelectric properties of the resulting hybrid films were characterized through measurements of the Seebeck coefficient, electrical conductivity, and thermal conductivity. The findings show that the thermoelectric performance of the PVA/SiO2 hybrid films is greatly improved by TiO2 nanoparticles are added to the rutile phase, with an optimal concentration (1%) of TiO2 nanoparticles. This study provides insights into the potential applications of TiO2 nanoparticles in enhancing the thermoelectric properties of hybrid materials and opens up avenues for further research in this area, and contributes to the growing body of knowledge on enhancing the thermoelectric properties of materials by incorporating TiO2 nanoparticles into hybrid films synthesized by the sol-gel method.
