compound introduction
LEB-PAni doped with water may be used as sensor to detect NOx2 and pathogen. 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. 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.
