| Application: | PANI-EB can form a nanocomposite with multi-walled carbon nanotubes (MWCNTs) that can be used to functionalize glassy carbon electrodes for the electro-sensitive detection of cadmium (Cd(II)) and lead (Pb(II)). Carbon nanofibers may be reinforced on PANI-EB to yield a specific capacitance of 95 F/g and a 92% retention over 3000 cycles as observed in supercapacitor applications. It may be used with heptamethyleneimine as an inhibitor to form stable fuel cell membranes. |
| Features and Benefits: | Undoped form of conducting polymer (non-conductive). |
| General description: | Polyaniline (emeraldine base) (PANI-EB) is an intrinsically conducting polymer (ICP) that can be formed by oxidative polymerization of aniline. Emeraldine base contains oxidized diimine and reduced diamine. PANI can be modified into the conjugating emeraldine base form by p-type doping with protonic acid. |
| 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. |
