Embodiment 1
[0024] (1) Clean indium tin oxide conductive glass (ITO) as the working electrode, use acetone, ethanol, and distilled water in an ultrasonic cleaning machine for 20 minutes each, and dry at 40°C for 2 hours. The cleaned ITO electrode is stored in a sealed bag for later use.
[0025] (2) Take conductive polyaniline (PANI) powder with nanofibrous morphology and dissolve it in formic acid to obtain a PANI formic acid solution with a concentration of 1 mg / mL. With PANI formic acid solution as the dispersion medium and acetonitrile as the dispersant, prepare the PANI sol with a concentration of 0.01g / L.
[0026] (3) Take the PANI sol into a beaker, fix the ITO electrode and the platinum sheet electrode (counter electrode), connect the platinum sheet electrode to the positive electrode, connect the ITO electrode to the negative electrode, connect the DC working power supply, control the deposition voltage to 50V, and the deposition time to 60s After the deposition is completed, ri...
