Enhanced Piezoelectric Performance of Highly-Aligned ZnO Nanorods Embedded in P(VDF-TrFE) Nanofiber Membranes

Polymers, Journal Year: 2025, Volume and Issue: 17(5), P. 585 - 585

Published: Feb. 22, 2025

Flexible and wearable electronics often rely on piezoelectric materials, Poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) membranes are popular for this application. However, their electromechanical performance is limited due to a relatively low coefficient. To address this, study investigates the incorporation of zinc oxide (ZnO) nanorods (NRs) into P(VDF-TrFE) nanofiber membrane matrix. ZnO NRs were synthesized doped well-aligned nanofibers using electrospinning with high-speed rotating drum. The impact NRs’ mass fraction properties was evaluated. Results show that maximum coefficient (d33) −62.4 pC/N, 9.5 times higher than neat P(VDF-TrFE), achieved. These enhanced demonstrated excellent in finger-tapping bending detection, making them promising large-scale flexible sensor applications electronics. This approach offers simple effective route improve materials devices.
