Embodiment 1

[0042] The present embodiment provides a preparation method of a triboelectric nanogenerator and a cellulose / animal hair composite material for a self-driven sensor, which specifically includes the following steps:

[0043] S1. Weigh 0.05g of cellulose and disperse it in 5mL of water to prepare a 1% cellulose solution;

[0044] S2. Wash the hair with water and ethanol, and dry it in a vacuum drying oven for 1 hour;

[0045] S3. Add hair of the same quality as cellulose to the solution in step S1, stir to fully disperse the hair in the solution, pre-freeze the mixed solution at -80°C for 1 hour, and cool the pre-frozen mixed solution at -80°C C, the pressure is freeze-drying under the condition of 0.4mBar for 3 days to obtain cellulose / hair aerogel;

[0046] S4. Compress the aerogel prepared in step S3 into a thin film with a thickness of 0.2 mm, that is, to obtain a cellulose / hair composite material for triboelectric nanogenerators and self-driven sensors.

Description

technical field [0001] The invention relates to the field of nano new energy, and more particularly, to a cellulose / animal hair composite material based on a triboelectric nanogenerator and a self-driven sensor and a preparation method thereof. Background technique [0002] Converting mechanical energy in life and nature into electrical energy through nanogenerators is a sustainable energy regeneration technology emerging in recent years. Compared with traditional piezoelectric nanogenerators, triboelectric nanogenerators have the advantages of high energy conversion rate, high output power, high sensitivity, high adaptability, and low cost, and thus have received extensive attention. The triboelectric nanogenerator is based on the charge transfer effect generated when two materials with different electron adsorption capacity are in contact, and a potential difference is generated when the two materials are separated, which leads to the flow of electrons in the external circ...
