Flexible high-entropy functional ceramics

-based film that can withstand ~180° folding with a bending strain and tensile elongation up to 4.80% and 5.29%, respectively. The crystalline/amorphous structure enables the production of a flexible dielectric capacitor with high permittivity (~35), good temperature stability and durability. This strategy offers research prototypes for customizing the microstructures of functional ceramics, advancing next-generation ceramics with flexibility.
