High-transparency flexible porous triboelectric material and preparation method thereof

The invention discloses a high-transparency flexible porous triboelectric material and a preparation method thereof. The preparation method comprises the following steps: dissolving cellulose acetatepowder in a mixed solvent of acetone and water to obtain transparent cellulose acetate solutions with different mass fractions; mixing the transparent cellulose solutions with a preheated polyethyleneimine solution under certain treatment conditions to obtain a uniform membrane casting solution; and blade-coating the membrane casting solution in a self-made template to form a membrane, standing the preformed membrane, and drying the preformed membrane in a drying oven to obtain a transparent membrane, namely the high-transparency flexible porous triboelectric material, after the solvent is completely evaporated. The environment-friendly triboelectric material disclosed by the invention has the advantages of light transmittance, strong triboelectric positive polarity, flexibility and porosity, and also has the char
