Abstract

The correlation between the effect of varying the acid dopant (sulfuric acid) concentration on the fractal dimension and electrical conductivity of polyaniline was determined. Polyaniline (PANI) doped in 0.5M, 1.25M and 1.75M H₂SO₄ were examined through a Scanning Electron Microscope (SEM) and their fractal dimension obtained with the use of the program ImageJ. It was found that an increase in the dopant concentration resulted in a decrease in both the fractal dimension and electrical conductivity.
