    Fabrication of Polyaniline-Based Nano Materials for the Application in Energy Harvesting and Sensing Devices
    (2020) Palsaniya, Shatrudhan
    PANI nanomaterials strongly depend on the distribution of nanofillers for property enhancement. Based upon these nanomaterials, a brief introduction of energy storage and sensing devices have been included in Chapter-1. Chapter-2 describes binary and ternary nanocomposites of PANI, G and MoS2. Among them, PANI-G-MoS2 ternary nanocomposite exhibits excellent electrochemical activity and enhanced cyclic stability. Chapter-3 describes GO, RGO, and α‒MnO2 based PANI functionalized binary and ternary nanocomposites. Herein, PANI-RGO-MnO2 has appeared an excellent candidate for high‒density energy storage material with superior dielectric strength. Chapter-4 presents a comparative study of binary and ternary nanocomposites of PA6, rGO, and PANI components. We have observed that PA6-rGO-PANI 1:2 shows an excellent electrochemical performance with improved cyclic stability, as compared to other composites. Further, fabricated symmetric supercapacitor devices also have demonstrated outstanding performance. Chapter 5 unveils ZnO (transition metal oxide), and RGO based PANI functionalized nanocomposites. In particular, PANI-RGO-ZnO 2:1 composite reveals a superior performance as an electrode material. Chapter-6 describes preparation of PANI-ES and PANI-EB thin film, deposited on glass and n-type Si wafer substrates using a vacuum evaporation technique. We have observed that deposition of PANI-EB is relatively easier than PANI-ES. Contrary to PANI-EB, PANI-ES thin-film shows better electrical conductivity. Hence, fabricated thin-film capacitors also have shown remarkable current density and energy density with the high percolation threshold. Chapter-7 presents a hierarchical mesostructure of PANI nanorods by incorporating SDS and F127 as structure-directing agents (SDAs). The PANI-SDS-F127 1:1 composition has shown higher glucose sensitivity with a lower detection limit, attributed to the synergistic effect of available organic components. Chapter 8 summarizes the thesis work, with an outlook for future study.
