Tribo-polarity Enhancement of Polyvinylidene Fluoride for Liquid-Solid Triboelectric Nanogenerator

In this study, polyvinylidene fluoride (PVDF) membrane enhanced tribo-polarity property by using functionalized graphene oxide (F-GO) for liquid-solid triboelectric nanogenerator (TENG). Utilizing 1H,1H,2H,2H-perfluorooctyltriethoxysilane, the surface of GO was functionalized by covalently grafting. The result was a significant improvement in the tribo-polarity of the membrane, which increased the power performance of F-GO/PVDF-based TENG. As a result, the power performance of this TENG creates 0.14 mW with only one water droplet.
