文摘

We report on the modifications induced in the structural, optical and electrical properties of polyaniline onto the ferrous oxalate composites of the polymer. Fourier transform infrared spectra, x-ray diffraction patterns and digital thermal analysis studies have been employed to associate the modifications induced in the polymer due to the enhanced dopant concentration. The studies revealed that the cation dopant may bond with the lone pair of N- of the polymer, making the polymer stretched and crystalline. The polymer has been greatly influenced at the maximum dopant concentration. It seems that the dopant has modified the initial conformation of the polymer, whereas the main chain has remained unchanged. The thermal studies also indicate that the polymer has been stabilized to a greater extent on doping.
