Embodiment 1
[0021] (1) Preparation of PANI / MnO2 composites
[0022] Dissolve 0.015mmolTPPS and 0.6mmol aniline in 2mL distilled water in an ice-water bath; then add 1mL, 0.6mol / L APS aqueous solution to the above mixture to initiate polymerization for 30s under magnetic stirring; then react until a greenish color is obtained After the reaction, the PANI gel was immersed in distilled water for 24 hours to remove excess APS; the product was dried in vacuum at 60°C to obtain a PANI gel. Disperse the gel in 30mL, 0.02mol / L KMnO4 aqueous solution; then add a certain amount of HCl solution to adjust the pH of the suspension to 1; then, hydrothermally treat the sample at 120°C for 20min to obtain the PANI / MnO2 complex . Finally, the resulting product was washed several times with distilled water and then dried at 60 °C.
