Editing Polyaniline (section)

==Potential applications==
The major applications are [[printed circuit board]] manufacturing: final finishes, used in millions of m<sup>2</sup> every year, [[antistatic agent|antistatic]] and [[electrostatic discharge materials|ESD coatings]], and corrosion protection.<ref name=Ullmann/><ref name="Wessling">{{cite journal|doi=10.3390/polym2040786|title=New Insight into Organic Metal Polyaniline Morphology and Structure|journal=Polymers|volume=2 |issue=4|pages=786–798|year=2010|last1= Wessling|first1=Bernhard|doi-access=free}}</ref> Polyaniline and its derivatives are also used as the precursor for the production of N-doped carbon materials through high-temperature heat treatment.<ref name="PANI-Carbon">{{cite journal |last1=Yin |first1=Xi |last2=Chung |first2=Hoon T. |last3=Martinez |first3=Ulises |last4=Lin |first4=Ling |last5=Artyushkova |first5=Kateryna |last6=Zelenay |first6=Piotr |title=PGM-Free ORR Catalysts Designed by Templating PANI-Type Polymers Containing Functional Groups with High Affinity to Iron |journal=Journal of the Electrochemical Society |date=3 May 2019 |volume=166 |issue=7 |pages=F3240–F3245 |doi=10.1149/2.0301907jes |bibcode=2019JElS..166F3240Y |osti=1512751 |doi-access=free }}</ref> Printed emeraldine polyaniline-based sensors have also gained much attention for widespread applications where devices are typically fabricated via screen, inkjet<ref>{{Cite journal|date=2008-12-15|title=Fabrication of an ammonia gas sensor using inkjet-printed polyaniline nanoparticles|url=https://www.sciencedirect.com/science/article/abs/pii/S0039914008005274|journal=Talanta|language=en|volume=77|issue=2|pages=710–717|doi=10.1016/j.talanta.2008.07.022|issn=0039-9140|last1=Crowley |first1=K. |last2=Morrin |first2=A. |last3=Hernandez |first3=A. |last4=Omalley |first4=E. |last5=Whitten |first5=P. |last6=Wallace |first6=G. |last7=Smyth |first7=M. |last8=Killard |first8=A. |url-access=subscription }}</ref> or aerosol jet<ref>{{Cite journal|last1=Fisher|first1=Christine|last2=Warmack|first2=Bruce J.|last3=Yu|first3=Yongchao|last4=Skolrood|first4=Lydia N.|last5=Li|first5=Kai|last6=Joshi|first6=Pooran C.|last7=Saito|first7=Tomonori|last8=Aytug|first8=Tolga|date=2021-04-19|title=All-aerosol-jet-printed highly sensitive and selective polyaniline-based ammonia sensors: a route toward low-cost, low-power gas detection|journal=Journal of Materials Science|volume=56 |issue=22 |pages=12596–12606 |language=en|doi=10.1007/s10853-021-06080-0|bibcode=2021JMatS..5612596F |osti=1798595 |s2cid=233303736 |issn=1573-4803}}</ref> printing.
