Eminence of oxidants on structural-electrical property of Polypyrrole

The chemical oxidative approach has been followed for the synthesis of two types of polypyrrole (PPy) using dissimilar oxidizing agent for example ammonium peroxydisulfate (APS) and ferric chloride (FeCl3). Afterward, electrical resistivity and morphological study have been carried out using two-probe technique and scanning electron microscopy (SEM), respectively. X-ray diffractometry techniques were used to know the crystalline or amorphous nature of the prepared polymers. Thermogravimetric analysis study tells about the thermal stability of the prepared polymer which has been identified in the nitrogen atmosphere. It has been observed that PPy prepared with APS and FeCl3 oxidant displays resistivity well in which FeCl3 shows higher conductivity of 2.22 x 10(- 4) S/cm than APS having a conductivity value of 0.16 x 10(- 4) S/cm. It has been found that 1 M and 2 M concentrations of monomer and FeCl3 oxidant, respectively, have achieved better thermal stability compared with APS.Please check the edits made to the article title and amend if necessary.Thermogravimetric analysis studies explain about the thermal stability of the prepared polymer which has been carried out in the nitrogen atmosphere.

Automated summary

Two types of polypyrrole (PPy) were synthesized using different oxidizing agents, namely ammonium peroxydisulfate (APS) and ferric chloride (FeCl3), through a chemical oxidative approach. The electrical resistivity and morphology of the synthesized polymers were examined using a two-probe technique and scanning electron microscopy (SEM) respectively. X-ray diffractometry techniques were employed to determine the crystalline or amorphous structure of the polymers. Thermogravimetric analysis in a nitrogen atmosphere indicated the thermal stability of the prepared polymers. It was observed that the PPy prepared with FeCl3 exhibited higher conductivity of 2.22 x 10(-4) S/cm compared to the conductivity of APS at 0.16 x 10(-4) S/cm. Additionally, 1 M concentration of the monomer and 2 M concentration of FeCl3 demonstrated higher thermal stability compared to APS.
