Polypyrrole (PPy), polyaniline (PANI) nanotubes, were prepared by core@ shell polymerisation with ZnO, Ag, and Fe₃O₄ nanoparticles to produce hybrid polymers i.e , PPy@(ZnO, Ag, Fe₃O₄) and PANI@(ZnO, Ag, Fe₃O₄). The hybrid polymers were characterized using infrared spectroscopy (IR) to confirm their chemical structures of polymers and using scanning & transmission electron microscopy (SEM and TEM) to confirm the morphology of the hybrid polymers and the nanotubes stricture.
The optical properties of the hybrid polymers were studied using a UV–visible spectrophotometer. The spectra showed broad absorption peaks in the range ( 383-386) nm and (430-433) nm for PANI@ZnO,Fe3O4,Ag and PPY@ZnO,Fe3O4,Ag respectively and the energy gaps of pure were found to be PPY and PANI 2.37eV and 2.5 eV respectively also showed that the energy gap decrease with incorporated nanoparticles.
The I-V characteristic of PANI and PPy and their core@ shell polymers with Zno,Fe3O4 and Ag nanoparticles were studied to determine how electricity travels in polymer membranes .The results showed a quasi-linear relationship between current and voltage, which indicates ohmic behavior, meaning that the electrical conductivity is stable and there are no large barriers that impede the transfer. The highest conductivity was observed for PANI @Zn (789x10-4 S/m) and PPY @Ag (273x10-4 S/m)
