Preparation of Nano Metal Oxides doped Polymeric Ternary Composites for Energy Storage Applications

Abstract

The need to conserve natural resources and manage energy use has led to a significant newlineincrease in the development of sustainable energy and energy storage applications in recent newlineyears. Unconventional energy sources included in next-generation automobiles and electronic newlinegoods include batteries, supercapacitors, and fuel cells. Energy storage device development has newlinebenefited greatly from the use of polymer-based nanocomposites. newlineHerein, the development of nano metal oxides doped polymer based ternary composites newlineis constructed via different synthesis techniques including sol-gel, solution casting and in situ newlinepolymerization. In our first work, we have designed PMMA/TiO2 and PMMA/TiO2atclay newlinenanocomposites by using the sol-gel technique. The designed device has achieved maximum newlineCsp of 364.13 F/g. It has obtained optimum ED of 129.26 Wh/kg at a PD of 2913.04 W/kg. The newlinedeveloped PTC-6 nanocomposite has retained 97% capacitance retention after 5k CV cycles. newlineIn another work, dielectric properties of PVDF/TiO2 and PVDF/TiO2/Clay newlinenanocomposites synthesized via solution casting technique are examined. The highest and#61541;and#61602; newlinevalues of PVDF/TiO2 and PVDF/TiO2/Clay nanocomposites are achieved as 2×103 and newline1.4×104 at 1 kHz, respectively. The maximum and#61541;and#61602;and#61602; of PFTC-6 nanocomposite is found to be newline4.04 at 1 kHz. This giant permittivity of the prepared ternary polymer-based nanocomposite newlinecould be a great pathway for the electronic industry. newlineIn another work, the dielectric behaviour of PVP/TiO2 and PVP/TiO2/f-MWCNT newlineternary nanocomposites re studied in order to project the material for energy storage newlineapplications. The designed PVP/TiO2 binary nanocomposite has a maximum dielectric newlineconstant value of 2.8×102 at frequency of 102 Hz. The highest dielectric permittivity of newline2.22×103 with minimal loss of 2.66 is observed for PVP/TiO2/f-MWCNT nanocomposite at newlinefrequency of 102 Hz, respectively. The highest and#61555;ac conductivity values of 4.45×10-5 S/m and newline4.83×10-3 S/m are obtained at 1 MHz for PVPT-5 and PVPTM-5 nanocomposites newlineKeywords: Nanocomposite; Metal oxi
