High-performance triboelectric nanogenerator based on MXene functionalized polyvinylidene fluoride composite nanofibers

Trilochan Bhatta et al.

Summary: In this study, electrospun MXene (Ti3C2Tx) functionalized Polyvinylidene fluoride (PVDF) composite nanofiber is proposed as a promising negative triboelectric layer for boosting triboelectric energy harvesting performance.
