Embodiment 1
[0033] Dissolve 3.2 g of ammonium persulfate in 70 mL of ethanol solution (ethanol: water = 2:5, volume ratio), and ultrasonically dissolve to form a mixed system A, which is cooled to 4°C for use; 5 mL of pyrrole monomer and 0.01 g bayberry tannin were dissolved in 50 mL ethanol solution (ethanol: water = 3:2, volume ratio) to obtain a mixture B, and then the two pieces were passed through a slicer to remove the grain layer (length × width × height: 6 cm×2.5 cm×0.5 mm) blue skins were soaked in the mixed solution B for 1 h to form the mixed system C; then after the mixed system C was cooled down to 4°C, the mixed system A was poured into the mixed system C and kept at 4°C Under reaction for 12 h. After the reaction was completed, the conductive leather was obtained, and the obtained conductive leather was placed in absolute ethanol and water for 6 h, and then dried at 60 °C.

[0041] Dissolve 3.2 g of ammonium persulfate in 70 mL of ethanol solution (ethanol: water = 2:5, volume ratio), and ultrasonically dissolve to form a mixed system A, which is cooled to 4°C for later use; 10 mL of pyrrole monomer and 0.01 g bayberry tannin were dissolved in 50 mL ethanol solution (ethanol: water = 3:2, volume ratio) to obtain a mixture B, and then the two pieces were passed through a slicer to remove the grain layer (length × width × height: 6 cm×2.5 cm×0.5 mm) blue skins were soaked in the mixed solution B for 1 h to form the mixed system C; then after the mixed system C was cooled down to 4°C, the mixed system A was poured into the mixed system C and kept at 4°C Under reaction for 12 h. After the reaction was completed, the conductive leather was obtained, and the obtained conductive leather was placed in absolute ethanol and water for 6 h, and then dried at 60 °C.
