    Synthesis and characterization of natural fiber/tungsten oxide nanostructure based paper electrode for smart window applications
    (UMT, Lahore, 2021) AYESHA FAROOQ
    Flexible electrodes are of great fascination in the modernity of smart technology for the application of countless energy conversion as well as energy storage devices such as lithium-ion batteries, solar cells and thin film transistors. For adaptable, flexible high tech gadgets, addressing the hereditary structure of metal oxide is incredibly effective. Traditional electrodes are inferior then flexible metal oxide-based paper electrodes on the basis of their environmental friendliness, variety, and nontoxicity. The addition of insulating natural fibers in paper electrodes, on the other hand, limits conductive characteristics. In the present work, hydrothermal method was used to modify the conductivity characteristics of lignocellulose (natural fibers) and tungsten oxide (WO3) based paper electrodes. The produced flexible and electronically conductive paper electrodes were characterized in detailed using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Cyclic Voltammetry (CV) and Ultraviolet-Visible (UV-Vis) Spectroscopy. The effective production of Tungsten Oxide (WO3) is confirmed by X-Ray diffraction (XRD), while the nanostructured geometry can be seen in the scanning microscopy (SEM). The composite formation was confirmed using Fourier Transform Infrared (FTIR), and cyclic voltammetry (CV) calculations were taken on all of the synthesized samples to investigate the electrochemical kinetics, with LC/WO3 exhibiting the best specific capacitance of 38.2μF/g. The optical band gap (2.58eV) of LC/WO3 is determined by using UV-Vis Spectroscopy. Because of their light weight, environmental friendly and improved electrochemical characteristics, these manufactured composites can be employed as flexible electrodes in energy storage applications and will be ideal for modern bendable and disposable energy storage systems.
