Polyaniline Description
Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. It is soluble in N-methyl-2-pyrrolidinone (NMP) and N,N′-dimethly propylene urea (DMPU). It can be processed into fibers from these solvents. PLB facilitates the formation of a conjugating system that can be used for a variety of semiconducting applications.

FAQs
Q1 What are the main properties of Polyaniline?
Polyaniline is known for its excellent electrical conductivity, which can be tuned by doping. It also has good chemical stability, particularly in its emeraldine salt form, and it exhibits high environmental stability. Polyaniline is a versatile material, available in both insulating and conducting forms depending on its oxidation state.
Q2 How is Polyaniline synthesized?
Polyaniline is typically synthesized by oxidative polymerization of aniline in the presence of an oxidizing agent, such as ammonium persulfate (APS) or iron chloride (FeCl3). The polymerization process leads to the formation of polyaniline in various oxidation states, which can be controlled by varying the polymerization conditions.
Q3 What is the role of doping in Polyaniline?
Doping is essential in modulating the electrical conductivity of Polyaniline. By introducing electron-donating or electron-withdrawing dopants, the oxidation state of the polymer is altered, which enhances its conductivity. Common dopants include acids like hydrochloric acid or camphorsulfonic acid.
