Embodiment 1

[0042] This embodiment provides a method for preparing a friction nanchrin generator and a self-driven cellulose / animal hair composite, which includes the following steps:

[0043] S1. Weigh 0.05 g of cellulose dispersion in 5 ml of water to prepare 1% cellulose solution;

[0044] S2. Wash the hair with water and ethanol and dry in a vacuum drying box;

[0045] S3. Add the hair of the quality of cellulose and the hair, stir the hair in the solution, stir the hair in the solution, pre-free of the mixed solution at -80 ° C for 1 h, and the mixed solution after pre-freeze is -80 °. C, the pressure is 0.4 mbar conditions for 3 days, resulting in cellulose / hair airgel;

[0046] S4. The airgel compression prepared by step S3 is a film having a thickness of 0.2 mm, i.e., a fibrous / hair composite material for friction nangers and self-driven sensors.

Embodiment 2

[0048] The method of preparing the composite material of the present embodiment refers to Example 1, and the difference is that the animal hair is rabbit hair, the mass of rabbit hair is the same as the cellulose, and the obtained composite is a cellulose / rabbit composite material.

Embodiment 3

[0050] This embodiment provides a method for preparing a friction nanchrin generator and a self-driven cellulose / animal hair composite, which includes the following steps:

[0051] Composite porous materials were prepared from the manufacture of cellulose.

[0052]S1. Weighing 0.15 g of cellulose dispersing 3% cellulose solution in 5 ml of water;

[0053] S2. Wash the hair with water and ethanol and dry in a vacuum drying box;

[0054] S3. In the cellulose solution in S1, 50% of the corner of cellulose is added, and the hair is stirred into the solution in the solution, and the mixed solution is pre-free to 1 h at -80 ° C, the mixed solution after preparation is at the temperature. For -80 ° C, the pressure is frozen for 3 days under 0.4 mbar conditions, resulting in airgel;

[0055] S4. The airgel compression prepared by step S3 is a film having a thickness of 0.2 mm, i.e., a fibrous / hair composite material for friction nangers and self-driven sensors.

Description

Technical field [0001] The present invention relates to the field of nano-new energy, and more particularly to a cellulose / animal hair composite material based on friction nano generator and self-driven sensor and its preparation method thereof. Background technique [0002] Through the nano generator to convert the mechanical energy of life and nature into electrical energy is an emerging sustainable energy regeneration technology in recent years. Compared to traditional piezoelectric nano generators, friction nanchronic generators have high energy conversion, high output power, high sensitivity, high adaptability, and low cost, etc., and have received extensive attention. The rubbing nano generator is based on two charge transfer effects generated when there are two materials having different electron adsorption capacity materials. When the two materials are separated, thereby causing electron flow in the outer circuit of the nano generator to form a current, and by two mater...
