Полианилин

Описание

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].

Использование

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.
