Abstract :
A variables range of conducting polyaniline (PANI) nanocomposites hostedby polyvinyl alcohol (PVA) in a form of film has been prepared by using ã-irradiation technique to Aniline hydrochloride (AniHCl)/PVA composites.The conductivity of the film showed consequence increase following theradiation dose from 10 to 50 kGy for each different concentration of themonomer blend AniHCl in PVA matrix which have exponential relation. Themaximum achieved dc conductivity ó(0) was 10-1 (S/m) at high concentrationof AniHCl and 50 kGy radiation dose, as being studied by LCR-meter. Thecomposite films structure has also been studied by Raman spectroscope,which reveals that there is a new chemical bond structure as imines group ofthe form C=N (polarons) species has been formed by radiation and givingrise to Raman shift at 1637 cm^-1. The intensity of Polarons was also beingincreased exponentially following the radiation dose leading to increase ofpolyaniline conductivity. Moreover the morphological structure of the filmswere scanned by Scanning Electron Microscopy SEM, which intern revealsthat the composite film is composed of polyaniline nanoparticles in the rangesize of 100 nm.
