The study aims to enhance the output performance of triboelectric nanogenerators by engineering interfacial polarization in MXene-polymer nanofibers.
Developed a TENG using MXene, hydroxypropyl methylcellulose (HPMC), and PVDF-HFP composite nanofibers.
Evaluated its performance under a mechanical driving force of 70 N and frequency of 6 Hz.
Assessed electrical output performance and stability through 15,000 contact-separation cycles.
Achieved a peak-to-peak open-circuit voltage of 1.02 kV.
Demonstrated a short-circuit current density of 0.133 A·m–2 and peak power density of 27.40 W·m–2 at 20 MΩ.
Maintained stable electrical output over extensive cycling while providing differentiated breathing waveforms.
