Question

Polyaniline is easily doped with
a) Reducing agent b) Acid c) Oxidizing agent d) Alkali​

Answer 1

Answer:

B) Acid

Explanation:

The best dopant is para-toluene sulfonic acid. The PAni colour changes from undoped "EB" (blue) to doped "ES" (green).

Answer 2

Polyaniline is easily doped with "Acid". The correct option is (b) Acid.

Explanation:

1. Polyaniline (PANI) is a continuous polymer and organic semiconductor of the semi-flexible rod polymer family.
2. These polymers have been popular since the 1980s due to their flexibility in electrical and mechanical properties.
3. Polyaniline is one of the most widely studied polymers.
4. PANI is a semi-doped conductor which easily reacts with an acidic medium, thus acids are used in doping the PANI.
