How do you calculate polyaniline yield?
Theoretical yield of polyaniline (A) = Mass of dried polyaniline sample (B) Percentage yield of polyaniline =(B/A) *100% = 4n e e -NHCỨ + 5x (NH4)2S2O8 228.18 g/mole CHCIN 129.59 g/mole H **- cje СІө CH20NCI, 435.36 g/mole +2n HC1+ 5n H2SO4.
What is the stable form of polyaniline?
Emeraldine is the most stable form of PANI, which could be oxidized to pernigraniline or be reduced to leucoemeraldine, interchangeably [12] .
How do you synthesis polyaniline?
Polyaniline (PANI) synthesis. PANI was synthesized by oxidative polymerization using 0.1 M anilinium hydrochloride (ANHC) in 1 M HCl and ammonium peroxydisulfate (APS) as oxidant agent (equimolar to aniline). The polymerization reaction was made in a cooled (0 °C–0.3 °C) and stirred reactor.
Why is polyaniline conducted?
Although one of the oldest polymers, polyaniline has only recently been looked upon as a promising conducting polymer. Polyaniline can be made conductive by partial oxidation of the fully reduced (leucoemeraldine base) form or by partial protonation of the half oxidized (emeraldine base) form.
How do you purify polyaniline?
The removal of impurities (such as byproducts related to doping, oxidant traces or oligomers of aniline) is imperative for the application of PANI in electronics or biomedical fields. The common strategies to purify PANI are centrifugation-based washing and dialysis.
Which monomers are used in synthesis of polyaniline?
The high selectivity of oxidative polymerization of two other heterocyclic monomers (thiophene and pyrrole) should be noted; their polymers (polythiophene and polypyrrole) are also conductive. The peculiar features of synthesis of these polymers have much in common with PANI synthesis.
What is the best solvent for polyaniline?
N-Methyl-pyrrolidone (NMP)
Yes, the best solvent for polyaniline is N-Methyl-pyrrolidone (NMP).
