Flexible Superamphiphobic Film for Water Energy Harvesting

A flexible superamphiphobic SiO2/poly (vinylidene difluoride-co-trifluoroethylene) (PVDF-TrFE) film is designed to harvest the electrostatic energy from water. The working mechanism of the water-triboelectric nanogenerator is based on the triboelectricity generated from the contact electrification between water and the superamphiphobic SiO2/P(VDF-TrFE) film. The maximum power density for harvesting water can be brought up to 62.5 mW m−2, which is able to charge a capacitor and sufficient to light up light emitting diodes.
