Modification of the dielectric friction layer materials is an ideal way to enhance output performance a triboelectric nanogenerator (TENG), but current research mostly focuses on metal-polymer or metal-SiO2 materials. In this work, we constructed different TENG models based polymer C x F y -SiO2 electret materials, and electronic properties contact surfaces were investigated using first principles. We found that charge transfer in occurred only at interface, it was partially affected by terminal atoms near SiO2 interface. The with O-terminated achieved more satisfactory effect. Among them, II-C3F6-O model exhibited highest amount because better hybridization II-C3F6 O layer. Our study showed instead adding types layers, varying configurations same layers alternative regulate transfer. Furthermore, strategy could provide new ideas for enhancing TENGs.

Fabrication of Tubular Electricity Nanogenerator with High Power Density by Bulk Effect

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Abstract Enclosed liquid‐solid triboelectric nanogenerators (LS‐TENGs) have gained widespread attention due to the advantages of self‐storage liquid and less susceptibility contamination, but are limited by low output power density. Here, a tubular bulk effect electricity nanogenerator (TBE‐ENG) is reported inserting an internal electrode with appropriate depth between fluorinated ethylene propylene (FEP) film glass cross‐section in tube. The TBE‐ENG can achieve current 5.0 mA peak density 2169 W m −3 after adding 1 M sodium chloride solution, which much higher than those enclosed LS‐TENGs previous studies. mechanism elucidated via equivalent capacitor model, effects spatial position, dielectric layer thickness, properties on performance well revealed combination experiments. Moreover, applicability its application for driving electronic devices demonstrated. This work lays groundwork design higher‐performance LS‐TENGs, greatly expands effect.
