Polyaniline Chemical Properties,Uses,Production

Description

Polyaniline (PANI) is one kind of conductive polymer. It has shown great potential as supercapacitors electrode due to its advantages such as environment friendly, inexpensive, various redox states and excellent electrical conductivity (30–200 S cm? 1). Unfortunately, the solubility of PANI in all kinds of solvents is very poor. Thus, it is really hard to assemble the PANI into sensors. Referring to its chemical structure, many benzene ring structures exist in the molecular backbone, which induce adjacent molecules to form hydrogen bonds, resulting in a high rigidity. Therefore, even a low-concentration solution shows a strong gelation tendency[1].

Uses

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.

Uses

The polymer acts as an anticorrosive additive. Epoxy paints may be modified using PAni-EB.

Uses

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)

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.

Advantages

Polyaniline (PANI) is one of the conducting polymers most used as an anti-corrosion coating. It has the following advantages over other conducting polymers: (1) it can be synthesized easily via chemical or electrochemical means, (2) it can be doped and undoped easily by treatment with aqueous acid and base, (3) it cannot be degraded easily, and (4) the aniline monomer is relatively cheap. The first report of its synthesis dates back to 1862, and its primary application was as a textile dye. It was only during the 1960s that PANI's electrical property was realized[2].
