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.
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.

Application

PANI-EB is a conjugating polymer that finds applications in organic light emitting diodes (OLEDs), anticorrosive coatings, chemical sensors and solar cells.

Features and Benefits

Undoped form of conducting polymer (non-conductive).

Storage Class

11 - Combustible Solids
