Embodiment 1

[0021] Accurately weigh 6.48g (0.06mol) o-phenylenediamine monomer and add it to glacial acetic acid, place it in a water bath at 40°C, and stir to promote its dissolution. Weigh 13.68g (0.06mol) of ammonium persulfate according to the oxidant monomer ratio of 1:1, transfer it to a 100mL beaker and add 6mL of deionized water to fully dissolve it. Add the oxidizing agent solution into the glacial acetic acid solution of the o-phenylenediamine monomer, and continue the reflux reaction for 72 hours. After the reaction is finished, filter and dry to obtain doped black powdery poly-o-phenylenediamine.

[0022] The yield of the o-phenylenediamine polymer obtained in this example was 2.59 g, and the yield was 40.0%. The electrical conductivity of the polymer powder measured by the tablet method is 1.8×10 -10 S / cm.
