Abstract

Different polyaniline samples that were doped using different mineral acids were known to have different conductivities. Scanning Electron Microscopy showed differences in the microstructures of the doped and undoped Pani samples. The images were used as the base images for computation of Fractal dimension using ImageJ. A significant correlation between the fractal dimension and conductivity of the Pani sample was observed. An increase in surface fractal dimension increases the conductivity of the samples. Furthermore, this study is significant on finding the fractal dimension of the differently doped polyaniline.
