There are no particular limitations on the temperature, time, or mixing method for mixing the oxidizing agent solution and the 5-membered heterocyclic compound.
A few minutes to several tens of minutes at room temperature is sufficient. After mixing, insoluble matter is separated and removed. As a separation method, a conventional method such as decantation or another method can be used. The homogeneous solution thus obtained is shaped into a certain shape by coating or pouring it onto a suitable base material.
Then, by removing the solvent, a conductive film can be obtained.
