Phase Separation and Low-pH Exposure Driven Self-Poled PVDF for Piezoelectric Energy Harvesters and Self-Powered IoT Sensors

Herein, we have solution-processed PVDF films crystallized into a polar β phase via electrostatic interaction with a polar solvent and its controlled demixing in a nonsolvent bath. Subsequently, the self-polarization alignment is ascertained on the treatment of these films in a low-pH aqueous soluti...
