Research Projects

Solid-state fractional order capacitors (SSFOC) are a field of research that focuses on developing SSFOCs with enhanced constant phase zone (CPZ) and constant phase angle (CPA) to be tunable over a broad range. These capacitors have potential applications in automatic voltage regulators, oscillators, circuit filters, and energy-storage/generation device modelings. SSFOCs can be fabricated using ferroelectric polymers and their nanocomposites, such as carbon nanotubes, reduced graphene oxide, MXenes, and molybdenum disulfide (MoS₂). The aim of this project is to develop SSFOCs with enhanced CPZ and CPA that can be tunable over a broad range. PVDF, a polycrystalline material with five different phases, is used as an interlinker between layered TMDCs and PVDF. The π (pi) electron cloud over the nitrogen atom can efficiently interact with the -CH2 group in PVDF through hydrogen bonding, further promoting the ferroelectric 'β' phase. After a rigorous literature review, major research gaps have been identified, and a systematic, feasible, time-bound research plan has been proposed. This includes functionalizing synthesized 2D transition metal dichalcogenides (TMDCs) layered nanostructures with PANI, studying changes in impedance magnitude, CPA, and CPZ with frequency and temperature, analyzing the type of conduction and relaxation mechanisms within and outside the CPZ, and analyzing the effect of light on SSFOC behavior.
