Enhanced Dielectric Constant and Breakdown Voltage in Polymer nanocomposite with 2D Fillers for of High Energy-density Storage Devices

The increasing use of electronic devices in the present era has demanded lightweight and portable high-capacity energy storage devices. Dielectrics are such types of materials that are used to store electrostatic energy by polarizing the materials under an applied electric field. However, dielectrics with high breakdown voltage and large polarization (dielectric constant) are crucial constituents to having high-energy storage devices. Here we have demonstrated the functional capacitors using polymers with 2D nanofillers such as h-BN, Mica, and MoS₂ and observed enhanced dielectric constant and breakdown voltage for the application of high-energy storage thin film capacitor devices.
