Overview

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) is a 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
PANI forms a conjugating polymeric system that can be used for a variety of semiconducting applications. It can be used in the fabrication of a variety of devices which include fuel cells, light emitting diodes supercapacitors, chemical sensors and rechargeable batteries. PAni-EB/Polyacrylonitrile (PAN) composite nanofibers were fabricated. The effect of the concentration of dopant and solvent on the morphology, conductivity and mechanical properties of the composites were studied. Preparation of PAni-EB/PAN nanoweb has also been reported.
