Decoupling Bulk Polarization and Interfacial Charge Processes in 2D Zn-HHTP MOF/PVDF Piezoelectric and Triboelectric Nanogenerators

This study demonstrates that incorporating 2D Zn–HHTP metal–organic frameworks into PVDF creates a tunable platform where piezoelectric and triboelectric nanogenerator performances are optimized at different filler concentrations (1 wt% and 3 wt%, respectively) because piezoelectric output relies on bulk polarization while triboelectric output depends on interfacial charge processes and surface properties.
