Abstract
The invention discloses a method for improving triboelectric output performance of a protein film by changing a protein structure. Indissolvable protein powder and a trace amount of another protein powder are co-dissolved in a strong alkaline aqueous solution and maintained for a period of time, and then acidifying treatment is performed to achieve neutral condition to allow charge redistribution to induce refolding of the protein, which results in burying of hydrophobic groups of the protein and exposure of charged groups. Therefore, the solubility of the protein is remarkably improved, and a uniform protein solution is formed under a neutral condition. The plant protein structure is changed through a pH cycle process, a surface group exposure condition is adjusted, and the output performance of the plant protein film is greatly improved.
