EMERALDINEBASEPOLYANILINE Use and Manufacturing
Polyaniline and its derivatives can be synthesized by chemical oxidation, condensation polymerization, adsorption polymerization and electrochemical polymerization. Among them, chemical oxidation polymerization and electrochemical polymerization are the most important. The chemical oxidative polymerization method uses the oxidant in the oxidant solution to oxidatively polymerize aniline in an acidic aqueous solution. At present, ammonium persulfate is mainly used as oxidant and hydrochloric acid is a system of protic acid. On the one hand, the proton acid provides the pH value required for the antiproton, and on the other hand, it also enters the polyaniline skeleton in the form of a dopant so that the polyaniline has certain conductivity. The polyaniline thus prepared is a black-green powder with a conductivity of 5-10 S/cm. When treated with sodium hydroxide or ammonia water, it becomes blue-black. The conductivity drops to 10-11S/cm and becomes an insulator. Polyaniline can be doped with protic acid and counter-doped with alkali. The doping process is not accompanied by the gains and losses of electrons on the main chain. After proton doping, the conductivity of polyaniline can reach 5-10S/cm.
Polyaniline has conductivity after being doped, and it also has photoelectric conversion properties and nonlinear optical properties. The application of polyaniline: disposable conductive polymer batteries; electronic devices Schottky diodes; optical devices and optical switches, optical storage, optical display devices; as sensors and detectors; solar cells.
