General description

Magnetic susceptibility of emeraldine base polyaniline was reported.
Polyaniline (emeraldine base) (PANI) is anintrinsic conductive polymer which consists of a ring structure attached with nitrogen substituted derivatives. It has an emeraldine type oxidation state that exists in the form of its base. It can be prepared by deprotonation of emeraldine hydrochloric acid and ammonium hydroxide. It is mainly used in the development of electrochemical devices.

Application

Emeraldine base polyaniline may be used as a corrosion protection undercoat on steel and iron. It may be used as a hole transporting layer in polymer light emitting diodes.
PANI forms a conjugating system that can be used in semiconducting applications. It can be used in a variety of other applications which include protective coating, hole transporting layer for organic electronics and chemical sensing.

Features and Benefits

Undoped form of conducting polymer (non-conductive).
