Enhancing the β-phase of PVDF by nano piezoceramic hybrid for advanced capacitive and energy storage application
Present work focussed on the preparation and characterization of ferroelectric ceramic-polymer composites, specifically using Poly Vinylidene Fluoride (PVDF) as the polymer host and PbZr0.48Ti0.52O3(PZT), Bi0.5Na0.5TiO3 (BNT) ceramics as the filler. The composites were prepared using the solution casting technique, and various properties were examined under different experimental conditions. The composites were characterized for various properties, including structural, microstructural, vibrational (FTIR-Fourier Transform Infrared), dielectric, and ferroelectric properties. XRD (X-ray Diffraction) analysis was used to observe the electroactive β-phase fraction in the composites. The microstructure of the composites was examined to understand the arrangement of the components. FTIR analysis provided insights into the mechanism of enhancing the β-phase and the interaction between negatively surface-charged ions of the PZT/BNT (BP) filler and the CH2 dipole of the PVDF polymer matrix. Dielectric constant variation with PZT/BNT (BP) filler concentrations was studied. The interplay between functional properties and the β-phase, likely related to ferroelectric behaviour, was discussed in detail. The electroactive β-phase fraction was observed to increase in the ternary composite PVDF/PZT/BNT (BPP). For PVDF/PZT (PP) composite concentration, β-phase fraction decreased because of percolation effect. The study explores the comprehensive characterization of ferroelectric ceramic-polymer composites, focusing on the interaction between the polymer matrix and piezoceramic (PZT/BNT) (BP) filler. The observed changes in properties, especially the electroactive β-phase fraction, provide valuable insights into the composition-structure-property relationships in these composites. The work sheds light on the potential applications and optimization of these composites for capacitive applications.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
