Synthesis of polyaniline in organic solvents

In organic solvents, a simple method to prepare polyaniline (PANI) was found. PANI was oxidatively synthesized using a small amount of iodine as an auxiliary agent for polymerization in organic solvents such as ethanol, dichloromethane, chloroform, hexane, and toluene. The chemical structure of the resultant PANI was confirmed with infrared absorption spectroscopy measurements. The electrical conducting function of the resulting PANI was examined using 4-point probe method. In the polymerization process, PANI-based polymer alloys with non-conjugated polymers can be prepared via polymerization in organic solvents with iodine.
