Electromechanical Performance and Stability of Flexible Energy‐Harvesting CeO2/Polyvinylidene Fluoride Piezoelectric Nanogenerators With Zn Doping

Rare Metals, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVDF) matrices with embedded nanostructured fillers are extensively used in piezoelectric nanogenerators (PENGs) for harvesting mechanical energy. In this study, we synthesized well‐defined zinc‐doped cerium oxide (Znx‐CeO2) nanocubes via hydrothermal process and deposited flexible Zn‐CeO2/PVDF films via supersonic ...
