Abstract
Recycling of random mechanical energy in the environment has attracted great research interest in recent years. Herein, we report a rotating triboelectric nanogenerator (rTENG) based on GO@PVDF composite film. Benefit from the effective accumulation of electrostatic charges on the PVDF layers, the as-prepared rTENG shows high output performance. Its peak open-circuit voltage (Voc) and short-circuit current (Isc) are 35 V and 7.5 μA, respectively, which are 3 and 3.5 times than pure PVDF based rTENG at 600 rpm, and the maximum power density calculated is 15.2 mW/m−2. Based on the as-prepared GO@PVDF-based rTENG, some practical applications are established, for example, lighting 12 led light bulbs to full brightness and sensing wind speed, which demonstrates the high feasibility and efficiency of the rTENG and manifests that the rTENG could be used in reusing random energy.
