Which strong acid is better to dope with in PANI synthesis process? Sulfuric acid or Hydrauchloric acid, and why?

10 October 2018 1 7K Report

Synthesize the PANI requires doping with acid and for oxidation APS in chemical polymerization process. But the selection of acid is a question...and its important to know details about doped/ dedoped PANI.

Mainul Morshed

according to the following quotation, Sulfuric acid is more suitable than the HCl acid to dope the PANI in terms of conductivity.

"The effect of various acids on the conductance of PANI. They observed that among various acids such as sulfuric acid, hydrochloric acid, sulfonic acid and carboxylic acid, only hydro- chloric acid and sulfuric acid appreciably enhance the conductance of PANI. Borole et al. compared the effect of and Cl- anions on the conductance of PANI. They found highest conductance for sulfate-doped PANI."
