Descripción general

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 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.

Aplicación

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.

Stretchable Electroluminescent Devices

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.
