Embodiment 1

[0043] This embodiment provides a preparation method of silk airgel for triboelectric nanogenerator, which specifically includes the following steps:

[0044] S1. Prepare a silk protein solution with a concentration of 2%, store the prepared solution at 4°C, pour 15mL of the silk protein solution into an aluminum plate with a diameter of 55mm, and freeze it in a mixed bath of acetone and dry ice for 10 minutes , and then pre-freeze at -40°C for 1 hour until freezing;

[0045] S2. Freeze-dry the pre-frozen solution at -80° C. for 3 days to obtain the silk protein airgel, and compress the obtained silk protein airgel into a thin film of 0.2 mm.

[0046] This embodiment also provides a method for preparing polyvinylidene fluoride airgel, which specifically includes the following preparation steps:

[0047] Y1. Dissolve 1g of polyvinylidene fluoride in 20mL of dimethylformamide to make a 5% solution, apply the prepared solution evenly on the glass surface, and soak it in a water ...

Embodiment 2

[0051] This example refers to the preparation method of Example 1, the difference is that: the concentration of the silk protein solution configured in step S1 is 1%; the freeze-drying temperature in step S2 is -50°C; the concentration of polyvinylidene fluoride in step Y1 10%.

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...
