“…An effective technique for the synthesis of various polymers is chemical oxidative polymerization. The monomers solution is incorporated with an oxidizer and a dopant at 0-5 C with constant stirring during this process 23 The POA was prepared through chemical oxidative polymerization, O-anisidine as a monomer, and commonly used initiators such as potassium iodate (KIO 3 ), 24 ammonium persulfate (NH 4 ) 2 S 2 O 8, 25 potassium persulfate (K 2 S 2 O 8 ), 26 potassium dichromate (K 2 Cr 2 O 7 ), 27 quinolinium fluorochromate (QFC) [C 9 H 7 NH(CrO 3 F)], 28 etc. This technique provides a thick coating or powder of POA which is segregated through the remaining mixture by filtration at a predetermined time and afterward washed with purified water, methanol and acetone until a steady mass is reached.…”

Poly(o‐anisidine) (POA) is from the conductive polymer family and derivative of polyaniline. It can be mainly synthesized in two routes, chemical synthesis produces a powdered polymer, whereas electrochemical synthesis produces thin films. The plain POA explored for the anticorrosive applications on aluminum, copper, and brass surface. The POA is also explored in nanoparticles and nanofibers form. Along with plain POA, the composites of POA are popular and various materials such as carbon nanotube, graphene, vanadium pentoxide, cerium dioxide, are explored for the synthesis of POA composites. The POA composites find application as catalyst, for anticorrosive coating, for conductivity and membrane applications. The composites are used for sensor, detector, ion exchange membrane, anticorrosive coating on steel and aluminum substrate. The various derivatives of POA such as poly(2‐anisidine), poly(aniline‐co‐2‐anisidine), poly(aniline‐co‐o‐anisidine‐co‐o‐toluidine), poly(aniline‐co‐o‐anisidine), and poly(o‐anisidine‐co‐o‐toluidine) are explored in the literature and they have shown better performance as compared to the plain POA in terms of anticorrosive coating as well as they used in development of sensors and detectors. The health hazards of POA is slightly touched at the end of the review hence the study gives the brief idea about POA, its composites, POA derivatives with its wide range of applications in various sectors.
