Ultrasonic-assisted ultrafast fabrication of polymer nanowires for high performance triboelectric nanogenerators

This study not only presents a novel ultrafast fabrication approach of polymer nanowires with aspect-ratio controllability and universal suitability, but also demonstrates the polymer nanowires’ application in mechanical energy harvesting of TENGs with enhanced performance.Graphical abstractA novel, ultrafast, ultrasonic-assisted fabrication technique of polymer nanowires has been developed for triboelectric nanogenerator. By controlling the ultrasonic times, the length and aspect-ratio of polymer nanowires on the surface of polymer can be tunable from 2 to 232. The assembly TENGs are capable of harvesting mechanical energy with electric output of 153 V and 23 μA. This study not only presents a novel ultrafast fabrication approach of polymer nanowires with aspect-ratio controllability and universal suitability, but also demonstrates the polymer nanowires’ application in energy harvesting of TENGs with enhanced performance.
