Abstract : We find from diffuse reflectance Vis/UV spectral studies of polyaniline (emeraldine base; EB) powder doped with camphorsulfonic acid (HCSA) that the free carrier tail characteristic of an extended coil conformation appears and increases gradually on mechanical shaking with KBr powder. We also find that the forces present during spin-casting of EB films have a significant effect on the value of the absorption maximum of the exciton peak.
