Triboelectric nanogenerators (TENGs) as energy harvesters have been extensively investigated due to their ability convert mechanical electricity through the effective coupling of triboelectrification and electrostatic induction. Herein, we introduce polydimethylsiloxane (PDMS)-based TENG prepared using ZnSnO3 (ZTO) nanostructure on surface-modified carbon nanotubes (SMCs), which shows high power density suitable different types practical applications in harvesting self-power system. with 0.3 wt% ZTO-SMC exhibits an output voltage 665.63 V a current 137.08 mA m−2, corresponding improvements 295% 453%, respectively, those pristine PDMS-based TENG. The peak is 10.57 W m−2 at load resistance 7 MΩ. formation mechanism ZTO SMCs (ZTO-SMC) its effect performance are demonstrated functional theory calculations.

This work gives scientific technical understanding not only heterostructure interface nanoengineering but also development polymer-based TENGs for use self-powered systems.
