Investigation of the Structural Change of Doped Polyaniline during Heat Treatment

Article Preview

Abstract:

Doped polyaniline (PANI) was synthesized by chemical oxidative polymerization of aniline in aqueous acidic medium with mixed sulfuric acid and 5-sulfosalcyclic acid as complex dopant , and ammonium peroxydisulfate as an oxidant, and heat treated at 150°C, 200°C, 250°Cand 300°C for 2 hours in vacuum. Different intrinsic and extrinsic structural changes due to heat treatment were determined from FTIR and XRD measurements. When PANI is subjected to heat treatment, different changes are taking place in the system like doping, dedoping (extrinsic), oxidation and changes in crystal structure (intrinsic). Mechanisms for doping, dedoping and oxidation, are proposed.
