Abstract
The development of polymer-based dielectric materials with high dielectric permittivity, low dielectric loss, and excellent thermal stability remains a significant challenge for advanced energy storage applications. In the present work, poly(3,4-ethylenedioxythiophene)-b-poly(ethylene glycol) (PEDOT-b-PEG), zeolite 13X, and nano-carbon black (CB) were individually incorporated into a polyvinylidene fluoride (PVDF) matrix using a solution-casting technique. The structural and morphological analysis were carried out by Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), and scanning electron microscopy (SEM) and confirmed the uniform dispersion of nanofillers in the PVDF matrix. The thermal stability was investigated by using thermogravimetric (TGA) analysis for the various nanofiller-incorporated nanocomposites, i.e., PVDF/zeolite13X, PVDF/CBNPs, and PVDF/PEDOT-b-PEG nanocomposites. The dielectric measurement including the dielectric constant (ε), loss tangent (tanδ), and AC conductivity (σac) was carried out in the 50 Hz–10 MHz frequency range at room temperature. The PVDF/zeolite13X nanocomposite displayed the best performance out of all nanocomposites, with a high ε and relatively low tanδ, showing its potential in energy storage applications. A Cole–Cole plot revealed a semicircular arc formation for the nanocomposite with zeolite 13X and CB. The present comparative study provides valuable insights into the role of conductive and porous nanofillers in tailoring the dielectric behaviour of PVDF and offers an effective strategy for the design of lightweight, flexible, and high-performance dielectric materials for next-generation energy storage applications.
期刊介绍：
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
