Abstract
A triboelectric nanogenerator (TENG) and a power generation device based on a plant fiber and a modified tribo-electronegative material is provided. A rotor is located inside a stator. An inner circumferential surface of the stator is provided with copper, and an outer circumferential surface of the rotor is provided with a tribo-electronegative material. The tribo-electronegative material is not in contact with the copper, and an air gap is formed between the tribo-electronegative material and the copper. The inner circumferential surface of the stator is further provided with a plant fiber brush. During rotation, the tribo-electronegative material scrapes the plant fiber brush to allow soft contact to transfer charges. The rotor is axially connected to a driving shaft of a waterwheel, and the TENG operates under an action of a water flow. The tribo-electronegative material is obtained by etching a film to form a nano-textured structure and depositing a fluorocarbon layer.
