▎ 摘　　要

NOVELTY - Triboelectric nanogenerator is arranged on the surface of the shroud, and has a flexible conductive layer (100), comprises a first surface (101) and a second surface (102) arranged oppositely, a first friction layer (200) on the first surface of the flexible conductive layer; and a second friction layer (300), located on the second surface of the flexible conductive layer. The first friction layer and the second friction layer both include composite nanomaterials and polydimethylsiloxane, and composite nanomaterials include molybdenum sulfide, zinc sulfide and graphene. USE - Triboelectric nanogenerator used for flow guiding device (Claimed). ADVANTAGE - Friction nano generator is arranged on the surface of the air guide sleeve, so that the air resistance coefficient is further reduced, the service life of the air guide sleeve is prolonged, and energy consumption such as wind friction and rainwater impact is recovered in an electric energy form. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Preparation method of a triboelectric nanomotor, for preparing the triboelectric nanogenerator, which involves: i. dispersing graphene in deionized water, adding sodium molybdate, zinc nitrate, and thiourea to mix evenly, adding it into a hydrothermal reactor at a first preset temperature and a first preset time, and performing centrifugal cleaning to obtain a composite nanopowder; ii. after mixing the composite nano-powder and polydimethylsiloxane, adding a curing agent to obtain a colloidal mixture; iii. placing part of the colloidal mixture in a mold, and after standing at a second preset temperature and a second preset duration, the first friction layer is obtained; iv. a flexible conductive layer is covered on the surface of the first friction layer, and another part of the colloidal mixture is covered on the side surface of the flexible conductive layer away from the first friction layer to obtain a second friction layer. (2) Flow guiding device has shroud and a triboelectric nanogenerator, triboelectric nanogenerator is covered on the surface of the shroud, flexible conductive layer is connected to a rectifier, so as to conduct the charges captured by the first friction layer and the second friction layer to the rectifier.
