Method for improving triboelectric output performance of protein film by changing protein structure

[0032] In the control group, the vegetable protein film was prepared, and the vegetable protein film was prepared by the deposition method: first, the preparation of the film-forming solution, the insoluble protein powder was dissolved in an appropriate solvent: water or ethanol aqueous solution, and then an appropriate amount of glycerol was added as a plasticizer. After heat treatment, the protein is denatured to obtain a more extended structure required for film formation, and finally the solvent is evaporated to obtain a protein film with uniform texture, certain transparency and good flexibility.

[0033] The experimental group prepared the vegetable protein film by using the deposition method: first, the film-forming solution was prepared by co-dissolving the insoluble protein powder and a trace amount of another protein in a strong alkaline aqueous solution (1-5% , w / w), after a short period of time under these conditions, acidification to neutrality to allow charge redis

[0037] Example 1

[0038]The first is the preparation of the experimental histone solution. 1.25g of insoluble rice glutenin was dispersed in 25mL of aqueous solution (5%, w / w), and 0.0125g of another variety of rice glutenin was added. By adding 1M hydrogen Sodium oxide was adjusted to pH 12, so that it was fully dissolved in strong alkali. After stirring for 3 h, 1 M hydrochloric acid was added to acidify the solution to pH 10.5, and then 0.1 M hydrochloric acid was used to adjust the solution to pH 7.5. The entire pH cycle process needs to be carried out under stirring conditions. Finally, the salts and other small molecular compounds in the protein solution were removed by dialysis to obtain the film-forming solution of the experimental group.

[0039] like figure 1 As shown, compared with the negative control group (rice gluten without any treatment was fully hydrated in water), the absolute value of the potential of the experimental histone solution was higher, indicati
