Polyanilin – Wikipedia
Polyanilin, Kurzzeichen PAni oder PANI, ist ein leitfähiges Polymer.Es findet v. a. Anwendung in der Endbeschichtung von Leiterplatten [6] und im Korrosionsschutz. [7] Polyanilin wird auch als „intrinsisch leitfähiges Polymer" (ICP), also selbstleitend, bezeichnet, weil es in seiner Salzform ohne weitere Zusätze leitend ist.
