Ion beam induced modifications in nitroso substituted polyaniline: Spectral and electrical studies

The effects of ion beam irradiation on optical, chemical and electrical properties of nitroso substituted polyaniline, polynitrosoaniline (N-PANI) have been investigated. N-PANI was irradiated with 100 MeV 28Si ions at different ion-fluences. The pristine and irradiated polymer samples were characterized by FT-IR, UV–visible spectroscopic techniques. The electrical conductivity studies were conducted on polymer samples. A significant change in optical band gap and room temperature electrical conductivity was observed in polymer samples after irradiation. The solubility of the polymer samples has also been tested in 1-methyl-2-pyrrolidone (NMP).
