Abstract
In this study, the piezoelectric nanogenerators (PENs) based on the PVDF (polyvinylidene fluoride)/PZT (lead zirconate titanate, the particle size of <1 µm) incorporated with MWCNT (Multiwalled Carbone Nanotube, Outer diameter: 10 nm, Inner diameter: 4.5 nm, and Length: 3–6 µm) were produced using the electrospinning method. An β-phase content of 96.56 % in PVDF electrospun composites was arrived at due to the synergistic effect of the PZT ceramics and the MWCNT nanoparticles. The experimental results showed that a PVDF/PZT/0.7 wt%MWCNT composite with a thickness of 145 μm based on the PEN had an electrical power efficiency (0.16 μW) approximately 1.3 times higher at a vibrational frequency of 20 Hz under a resistive load of 46 KΩ as compared to that of the PEN based on the PVDF/PZT composite (0.12 μW). The PVDF/PZT/MWCNT-based PENs have promising potential for flexible energy transmission and structural health monitoring. © 2024 Elsevier B.V.
