The friction nano electric generator prepared by assembling the silk protein aerogel and the polyvinylidene difluoride aerogel has the advantages high unit area output powerand stable output performance.

Description

technical field [0001] The invention relates to the technical field of new nano-energy, and more specifically, relates to a silk protein airgel for a frictional nanometer generator, a preparation method thereof, and a frictional nanometer generator. Background technique [0002] Nanogenerators can convert mechanical energy in life and nature into electrical energy, which is a new sustainable energy regeneration technology emerging in recent years. Compared with traditional piezoelectric nanogenerators, triboelectric nanogenerators have the advantages of high energy conversion rate, output power, high sensitivity, high adaptability, and low cost, so they have received extensive attention. The working principle of the triboelectric nanogenerator is: based on the charge transfer effect generated when two materials with different electron adsorption capabilities are in contact, a potential difference is generated when the two materials are separated, which leads to the flow of e...
