Abstract
Cellulose is attractive for in fabricating renewable triboelectric nanogenerators (TENGs) due to its lightweight, flexibility, renewability, and biodegradability. However, the insufficient functional groups and weak polarization on the surface restrict its progress towards high-performance TENGs. Therefore, this research has developed flexible environment-friendly TENGs with significant output performance based on polyvinyl alcohol (PVA)/graphene oxide (GO) and cellulose films. Furthermore, the specific contact surface area of the films is improved by patterning rectangular dots using a photolithography technique. Moreover, the concentration of GO, size of friction layers, and thickness are optimized in terms of triboelectric output performance. The scanning electron microscope is used to observe the surface morphology of the prepared TENGs films. We believe that the fabricated TENGs have the potential to be applied for self-powered biomedical applications.
