Usage

Description

Polyaniline (PAni) is a conductive polymer composed of repeating imino-1,4-phenylene units. It can be prepared by protonation of PAni emeraldine base (PAni-EB), which forms at pH>7. Its unique properties make it suitable for various applications across different industries.

Uses

Used in Electronics Industry:
Polyaniline is used as a conductive polymer for chemical vapor sensors, supercapacitors, and biosensors. It is also utilized in the manufacturing of electrical conducting yarns, antistatic coatings, electromagnetic shielding, flexible electrodes, and printed circuit boards.
Used in Energy Storage and Conversion:
PAni facilitates the formation of a conjugating system that can be used for a variety of semiconducting applications. It is employed in the fabrication of fuel cells, light-emitting diodes, supercapacitors, chemical sensors, and rechargeable batteries.
Used in Antistatic and ESD Coatings:
Polyaniline is used as an antistatic and electrostatic discharge (ESD) protective coating, providing effective solutions for various industries to prevent damage caused by static electricity.
Used in Corrosion Protection:
The polymer acts as an anticorrosive additive, with epoxy paints being modified using PAni-EB. Its mechanism against corrosive agents has been explained in a study, demonstrating its potential in corrosion protection applications.
