Special Issue Information

Dear Colleagues,

We are preparing a Special Issue titled "Piezoelectric, Ferroelectric, and Dielectric Materials: Properties and Related Applications", Guest-Edited by Guangzhi Dong, to be published in [Materials] (IF: 3.4, ISSN 1996-1944).

Piezoelectric, ferroelectric, and dielectric materials have diverse functionalities that enable numerous applications, ranging from piezoelectric sensing to dielectric energy storage, which have attracted extensive research and development interests. This Special Issue will publish experimental and theoretical papers aiming to understand piezoelectric, ferroelectric, and dielectric properties, as well as their associated phenomena, in addition to applied papers dealing with the utilization of these materials in devices and systems.

This Special Issue includes—but is not limited to—the following areas:

  • The fundamentals of piezoelectric, ferroelectric, dielectric, and electrostrain properties.
  • Property characterization and property–structure relationship studies.
  • Advances in processing techniques for high-performance functional materials.
  • New systems, including ceramics, crystals, thin/thick films, and composites.
  • Industrial applications of piezoelectric, ferroelectric, and dielectric materials, including piezoelectric transducers/sensors, ferroelectric memory devices, electrostrictive actuators, dielectric energy storage applications, etc.
  • Challenges in and perspectives of development.

For this Special Issue, we invite authors to contribute research articles or reviews on the broad range of topics listed above.

Electrostatic capacitors, with the advantages of high-power density, fast charging–discharging, and outstanding cyclic stability, have become important energy storage devices for modern power electronics. However, the insulation performance of the dielectrics in capacitors will significantly deteriorate under the conditions of high temperatures and electric fields, resulting in limited capacitive performance. In this paper, we report a method to improve the high-temperature energy storage performance of a polymer dielectric for capacitors by incorporating an extremely low loading of 0.5 wt% carbon quantum dots (CQDs) into a fluorene polyester (FPE) polymer. CQDs possess a high electron affinity energy, enabling them to capture migrating carriers and exhibit a unique Coulomb-blocking effect to scatter electrons, thereby restricting electron migration. As a result, the breakdown strength and energy storage properties of the CQD/FPE nanocomposites are significantly enhanced. For instance, the energy density of 0.5 wt% CQD/FPE nanocomposites at room temperature, with an efficiency (η) exceeding 90%, reached 9.6 J/cm3. At the discharge energy density of 0.5 wt%, the CQD/FPE nanocomposites remained at 4.53 J/cm3 with an efficiency (η) exceeding 90% at 150 °C, which surpasses lots of reported results. Full article
