历史

As described byAlan MacDiarmid, the first definitive report of polyaniline did not occur until 1862, which included anelectrochemicalmethod for the determination of small quantities of aniline.

从20世纪早期开始, occasional reports about the structure of PANI were published. Subsequent to his investigation of other highly-conductive organic materials, MacDiarmid demonstrated the conductive states of polyaniline which arose upon protonic doping of the emeraldine form of polyaniline. Conductive polymers such as polyaniline remain of widespread interest, providing an opportunity to address fundamental issues of importance to condensed matter physics, including, for example, the metal-insulator transition, the Peierls Instability andquantum decoherence.
