Usage

Uses

Different sources of media describe the Uses of 25233-30-1 differently. You can refer to the following data:
1. Conductive polymerPolyaniline is used in chemical vapor sensors, supercapacitors and biosensors. It is also useful for manufacture of electrical conducting yarns, antistatic coatings, electromagnetic shielding, flexible electrodes and printed circuit board. Further, it is used in antistatic and ESD coatings and corrosion protection.
2. PLB facilitates the formation of a conjugating 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, super capacitors, chemical sensors(10) and rechargeable batteries.(11)
3. The polymer acts as an anticorrosive additive. Epoxy paints may be modified using PAni-EB.

Definition

ChEBI: A macromolecule composed of repeating imino-1,4-phenylene units.

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.
