FERROELECTRETS BASED ON SPACE-CHARGE POLYMER ELECTRETS

Abstract

Ferro/Piezoelectrets are cellular electrets exhibiting significant piezoelectric effect. The matrix of the piezoelectret may be space-charge electret made of nonpolar polymers or/and oriented-dipole electrets made of polar polymers with intrinsic dipoles. This article will delve into the physical principles of space-charge ferroelectrets, their fabrication techniques, and piezoelectric properties, as well as their applications in the field of flexible electronic devices.
