Abstract
Thermal characteristics of chemically synthesized polyaniline (EB) powder have been investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), modulated DSC (MDSC), wide angle X-ray diffraction (WAXD), FTIR spectra, solid MS spectrum, and solubility tests. The exothermic peak measured both in conventional DSC and MDSC was a non-reversing chemical cross-linking reaction and was further confirmed by wide angle X-ray, FTIR, and solubility tests. Two glass transitions (Tg), ∼70°C and ∼250°C, in polyaniline (EB) powder, were observed for the first time using MDSC during the process of heat treatment. These results clearly demonstrate that the morphology of polyaniline (EB) powder is changed by thermal treatment in the range of 185–350°C.
