Abstract

Recently, energy harvesting and sensing systems have introduced innovative approaches like utilizing plastic waste as a raw material for advanced functional materials. This research assesses the applicability of poly (vinylidene fluoride) (PVDF)-based terpolymer films in developing hybrid energy systems by improving the film characteristics through the incorporation of reduced graphene oxide (rGO) sheets and ferroelectric potassium niobate (KNbO₃) nanoparticles into the terpolymer matrix. An energy source was constructed using a plastic face wash container, which served as a substrate, coated with a terpolymer nanocomposite layer for the investigation of the energy harvesting behaviors of the films. COMSOL Multiphysics software was used to model and simulate the contact and separation modes of the device for analyzing the potential distribution. Additionally, the tests were performed without an air gap to determine the effectiveness of the films in utilizing piezoelectric energy. The study also examined possible real-time applications of these nanocomposite films.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
