'''Polyaniline''' ('''PANI''') is a [[Conductive polymer|conducting polymer]] and [[organic semiconductor]] of the [[semi-flexible rod polymer]] family. The compound has been of interest since the 1980s because of its electrical conductivity and mechanical properties. Polyaniline is one of the most studied conducting polymers.<ref>{{cite book|author1=Okamoto, Yoshikuko |author2=Brenner, Walter |year=1964|title=Polymers|pages=125–158|chapter=Ch. 7: Organic Semiconductors|publisher=Reinhold}}</ref><ref>{{cite journal|doi=10.1103/RevModPhys.73.681|title=Nobel Lecture: Semiconducting and metallic polymers: The fourth generation of polymeric materials|journal=Reviews of Modern Physics|volume=73|issue=3|pages=681–700|year=2001|last1=Heeger|first1=Alan|bibcode=2001RvMP...73..681H|citeseerx=10.1.1.208.7569}}</ref>
