| General description: | Polyaniline (emeraldine base) (PANI-EB) is a conductive polymer that can be chemically synthesized from aniline by oxidative polymerization of ammonium peroxydisulfate in acidic solution. It is widely used in electronics and optoelectronic applications. |
| General description: | Polyaniline (PAni) emeraldine salt can be prepared by protonation of PAni emeraldine base (PAni-EB). PAni-EB forms at pH>7. Its mechanism against corrosive agents has been explained in a study. |
