Synergistic Processes for Microstructure Engineering and Enhanced Dielectric Functionality in PVDF‐Based Systems

Macromolecular Rapid Communications, Volume 47, Issue 1, 9 January 2026.
This work shows that tuning solvent polarity and evaporation rate during casting significantly improves the microstructure and dielectric properties of PVDF‐based co‐ and ter‐polymers films. Using highly polar, fast‐evaporating solvents enhances crystallinity, electroactive phase formation, and dielectric performance, offering a simple, energy ...

Electrocaloric effect and freezing temperature in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic [PDF]

Journal of Advanced Dielectrics, 2016
The electrocaloric effect (ECE) is studied in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic by using an “indirect method”. The electric dependence for the polarization (hysteresis loops) has been obtained for several temperatures ...

Anomalous Refractive Index Modulation and Giant Birefringence in 2D Ferrielectric CuInP2S6

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
An unprecedented anomalous thickness‐dependent change in refractive index is reported in CuInP2S6 (δn$\delta{\rm n}$∼23.2%). Furthermore, CuInP2S6 also exhibits giant birefringence in the blue‐ultraviolet regime (|nOOP ‐ nIP|∼1.24), the largest of any known material within this wavelength regime.

Coexisting Phases in NaNbO3 Thin Films Influenced by Epitaxial Strain and Size Effects

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Coherently strained NaNbO3 thin films are synthesized across a range of thicknesses, enabling the study of size effects under epitaxial strain in antiferroelectric thin films without relaxation. Competing antiferroelectric‐ferroelectric phases are observed, leading to the stabilization of phase coexistence, multistate switching with strong retention ...

Optical Control of the Thermal Conductivity in BaTiO3

Advanced Functional Materials, Volume 35, Issue 48, November 26, 2025.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

Airbrushing: A Novel Method for Preparation of High‐Emissivity Black Coating for Infrared Measurements

Advanced Materials Interfaces, Volume 12, Issue 21, November 10, 2025.
This study showcases the airbrush method, a novel coating technique for the preparation of thin black paint coatings for infrared camera measurements. Using the method, coatings with an emissivity of 0.95, and as thin as 3 µm can be prepared. The method is affordable, non‐destructive, and can be prepared onto a wide range of substrates while ...
